Percentage in background

I'm kind of stuck with a problem and I hope you can help me. Im developing an Android application with Android Studio.
I have a TableLayout with 2 elements. The first column is a LinearLayout with a percentage painted in the background, and the second column, just a simple textview (for the example, I put two rows in it).
I have solved the problem with XML representation, and I need to do the same but programmatically. Here is my XML:
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id = "#+id/tableLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/orionBackground"
android:orientation="horizontal"
android:weightSum="100">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="30"
android:background="#color/orionRed">
<TextView
android:layout_width="30dp"
android:layout_height="wrap_content"
android:text=""
android:layout_gravity="right"
android:textColor="#color/orionWhite"/>
</LinearLayout>
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello"
android:layout_gravity="right"
android:background="#color/orionBackground"
android:textColor="#color/orionWhite"/>
</TableRow>
<TableRow
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/orionBackground"
android:orientation="horizontal"
android:weightSum="100">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="50"
android:background="#color/orionRed">
<TextView
android:layout_width="30dp"
android:layout_height="wrap_content"
android:text=""
android:textColor="#color/orionWhite"/>
</LinearLayout>
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="There"
android:layout_gravity="right"
android:background="#color/orionBackground"
android:textColor="#color/orionWhite"/>
</TableRow>
</TableLayout>
I need to do the same but programmatically and I don't know how could be wrong with what Im doing. Here is my code:
TableLayout table = (TableLayout)findViewById(R.id.tableLayout);
/*TextView*/
TextView textViewHelloWorld = new TextView(getBaseContext());
textViewHelloWorld.setText("");
textViewHelloWorld.setLayoutParams(
new ViewGroup.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT));
textViewHelloWorld.setTextColor(Color.parseColor("#FFFFFF"));
/*Child Layout*/
LinearLayout linearLayout = new LinearLayout(getBaseContext());
/*Here I set the percentage of the LinearLayout to 10*/
LinearLayout.LayoutParams params1 = new LinearLayout.LayoutParams(
0, ViewGroup.LayoutParams.MATCH_PARENT, 10f);
linearLayout.setLayoutParams(params1);
linearLayout.setBackgroundColor(Color.parseColor("#A23934"));
/*Textbox Added | I tested before the above line*/
linearLayout.addView(textViewHelloWorld);
/*Parent Layout*/
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT,100f);
LinearLayout parentLayout = new LinearLayout(getBaseContext());
parentLayout.setOrientation(LinearLayout.HORIZONTAL);
/*Finally, I added the LinearLayout into de parent LinearLayout*/
parentLayout.addView(linearLayout,params);
TableRow rowHeader = new TableRow(getBaseContext());
TableRow.LayoutParams params10 = new TableRow.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
rowHeader.setLayoutParams(params10);
/*Then, the linear layout is Added into de TableRow*/
rowHeader.addView(parentLayout);
/*And added to the row*/
table.addView(rowHeader);
Visually, this is how I need to see it:
What I want to accomplish
This is for an app that will show the percentage of amount in a order book of cryptocurrencies.
My issue is that my solution print the whole background and should be print only a part of the background. The image above, prints the percentage, 30 and 60, defined by the layout_weight attribute, but when I do it programmatically doesnt work at all.
Why isnt working?
I really hope you can help me with this.
Thanks a lot

try to set elevation to TextView like ViewCompat.setElevation(textViewHelloWorld, 10);
so this be like
TextView textViewHelloWorld = new TextView(getBaseContext());
textViewHelloWorld.setText("sample text");
textViewHelloWorld.setLayoutParams(
new ViewGroup.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT));
textViewHelloWorld.setTextColor(Color.parseColor("#FFFFFF"));
ViewCompat.setElevation(textViewHelloWorld, 10);

Adding TableRow programmatically in Android

I'm working in an Android application and I want to add a TableRow programmatically in my TableLayout.
I have this TableLayout:
<TableLayout
android:id="#+id/details_table"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableRow>
<TextView
android:text="4686"
android:layout_width="wrap_content"
android:layout_column="0"
android:layout_weight="1"
android:textSize="7px"
android:textColor="#color/black" />
<TextView
android:text="sdhiuf osdfh isdhf ihdf"
android:layout_width="wrap_content"
android:layout_column="1"
android:layout_weight="1"
android:textSize="7px"
android:textColor="#color/black" />
<TextView
android:text="2"
android:layout_width="wrap_content"
android:layout_column="2"
android:layout_weight="1"
android:textSize="7px"
android:textColor="#color/black" />
<TextView
android:text="UN"
android:layout_width="wrap_content"
android:layout_column="3"
android:layout_weight="1"
android:textSize="7px"
android:textColor="#color/black" />
</TableRow>
and I want to add this exactly TableRow programmatically.
I'm trying something like this:
TableLayout detailsTable = (TableLayout) l.findViewById(R.id.details_table);
for(Nfce_Product nfceProduct : nfceProducts){
TableRow tableRow = new TableRow(getActivity());
TextView tvProductCode = new TextView(getActivity());
tvProductCode.setLayoutParams(new TableRow.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT, 1f));
tvProductCode.setText(nfceProduct.getProduct_code());
tvProductCode.setTextSize(TypedValue.COMPLEX_UNIT_PX, productDetailsTextSize);
tvProductCode.setTextColor(getResources().getColor(R.color.black));
TextView tvProductDescription = new TextView(getActivity());
tvProductDescription.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT, 1f));
tvProductDescription.setText(nfceProduct.getProduct_description());
tvProductDescription.setTextSize(TypedValue.COMPLEX_UNIT_PX, productDetailsTextSize);
tvProductDescription.setTextColor(getResources().getColor(R.color.black));
TextView tvProductAmount = new TextView(getActivity());
tvProductAmount.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT, 1f));
tvProductAmount.setText(String.valueOf(nfceProduct.getAmount()));
tvProductAmount.setTextSize(TypedValue.COMPLEX_UNIT_PX, productDetailsTextSize);
tvProductAmount.setTextColor(getResources().getColor(R.color.black));
TextView tvProductMetric = new TextView(getActivity());
tvProductMetric.setLayoutParams(new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT, 1f));
tvProductMetric.setText(nfceProduct.getProduct_metric());
tvProductMetric.setTextSize(TypedValue.COMPLEX_UNIT_PX, productDetailsTextSize);
tvProductMetric.setTextColor(getResources().getColor(R.color.black));
tableRow.addView(tvProductCode);
tableRow.addView(tvProductDescription);
tableRow.addView(tvProductAmount);
tableRow.addView(tvProductMetric);
detailsTable.addView(tableRow);
}

Here is my own answer to my own dynamically created TableRow question. I think my answer is detailed enough, you should have no problems taking it as your own! My issue involved not only dynamically creating TableRows, but also being able to touch each row and have something happen. I've gone further than that nowadays to make each CELL separately clickable.
Edit: You need to have a separate TableRow XML file that you can access, separate from the actual TableLayout you're trying to dynamically populate.
Edit2: I should probably try to make an actual solution for you, so that you see what I'm talking about:
First, create (or keep) your XML file containing your TableLayout. Second, Create a separate TableRow XML file.
(This is your potential tablerow.xml file)
<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:focusable="true" >
<TextView
android:id="#+id/tableCell1"
android:layout_width="wrap_content"
android:layout_column="0"
android:layout_weight="1"
android:textSize="7px"
android:textColor="#color/black" />
<TextView
android:id="#+id/tableCell2"
android:layout_width="wrap_content"
android:layout_column="1"
android:layout_weight="1"
android:textSize="7px"
android:textColor="#color/black" />
<TextView
android:id="#+id/tableCell3"
android:layout_width="wrap_content"
android:layout_column="2"
android:layout_weight="1"
android:textSize="7px"
android:textColor="#color/black" />
<TextView
android:id="#+id/tableCell4"
android:layout_width="wrap_content"
android:layout_column="3"
android:layout_weight="1"
android:textSize="7px"
android:textColor="#color/black" />
</TableRow>
Now... back to your actual code!
for (Nfce_Product nfceProduct : nfceProducts) {
final TableLayout detailsTable = (TableLayout) findViewById(R.id.details_table);
final TableRow tableRow = (TableRow) getLayoutInflater().inflate(R.layout.tablerow, null);
TextView tv;
//Filling in cells
tv = (TextView) tableRow.findViewById(R.id.tableCell1);
tv.setText(nfceProduct.getProduct_code());
tv = (TextView) tableRow.findViewById(R.id.tableCell2);
tv.setText(nfceProduct.getProduct_description());
tv = (TextView) tableRow.findViewById(R.id.tableCell3);
tv.setText(nfceProduct.getAmount());
tv = (TextView) tableRow.findViewById(R.id.tableCell4);
tv.setText(nfceProduct.getProduct_metric());
//Add row to the table
detailsTable.addView(tableRow);
} //End for
If you still need/want to change the text size and color, you can do that after the setText() line and before you do findViewById again. If you want to have column headers that basically say Code, Description, Amount, and Metric, make a TableRow inside the TableLayout like you have currently. The TableRows created programmatically will fall in line after that "header" row.

Programmatically placing a layout view inside a table view

I have a layout file called row which is basically a wrapper for how i want my row to look like
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TableRow
android:id="#+id/tableRow"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<TextView
android:id="#+id/oid"
android:layout_width="0dp"
android:layout_weight="1" android:background="#dcdcdc"
android:textColor="#000000"
android:padding="5dip"
/>
<TextView
android:id="#+id/value"
android:layout_width="0dp"
android:layout_weight="1" android:background="#d3d3d3"
android:textColor="#000000"
android:padding="5dip"
/>
<TextView
android:id="#+id/type"
android:layout_width="0dp"
android:layout_weight="1" android:background="#dcdcdc"
android:textColor="#000000"
android:padding="5dip"
/>
</TableRow>
</LinearLayout>
Now i d like to be able to create a row using this layout and place it in my table that is defined in the fragment layout. This is my current code for creating a row(it doesn't use the row layout file) and adding it to the table, but the row is not formatted as i d like it to be.
TableLayout varbindTable = (TableLayout) view2.findViewById(R.id.tableLayout1);
TableRow row = new TableRow(getActivity());
row.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.MATCH_PARENT));
varbindTable.addView(row);
TextView name = new TextView(getActivity());
name.setText(((EditText)view.findViewById(R.id.oid)).getText().toString());
name.setTextColor(Color.BLACK);
name.setLayoutParams(new TableRow.LayoutParams(
0,
TableRow.LayoutParams.MATCH_PARENT));
TextView value = new TextView(getActivity());
value.setText(((EditText)view.findViewById(R.id.value)).getText().toString());
value.setTextColor(Color.BLACK);
value.setLayoutParams(new TableRow.LayoutParams(
0,
TableRow.LayoutParams.MATCH_PARENT));
TextView type = new TextView(getActivity());
type.setText(((Spinner)view.findViewById(R.id.data_type_spinner)).getSelectedItem().toString());
type.setTextColor(Color.BLACK);
type.setLayoutParams(new TableRow.LayoutParams(
0,
TableRow.LayoutParams.MATCH_PARENT));
row.addView(name);
row.addView(value);
row.addView(type);

Well, at first glance, the issue looks like your settings are different in the 2 examples. In the xml, you are using layout_width="0dp" and layout_weight="1". However, in the code you are using MATCH_PARENT.
Closest example I could find:

Android: Dynamically added TextView not wrapping text

Dynamically adding TextViews to this layout results in text not being wrapped.
<!-- R.layout.description_card -->
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout_InfoShow"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="#dimen/table_row_padding_bottom" >
<TableLayout
android:background="#drawable/card_bg"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TableRow
android:id="#+id/TableRow_DescriptionTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/DescriptionTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-light"
android:textSize="#dimen/page_name_size"
android:text="Loading data..." />
</TableRow>
<TableRow
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/DescriptionTitle">
<LinearLayout android:id="#+id/LinearLayout_Description"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- Dynamically added TextView here -->
</LinearLayout>
</TableRow>
</TableLayout>
</LinearLayout>
I dynamically add the TextViews to this layout using these methods:
View view = inflater.inflate(R.layout.description_card, null);
TextView title = (TextView) view.findViewById(R.id.DescriptionTitle);
LinearLayout description = (LinearLayout) view.findViewById(R.id.LinearLayout_Description);
ArrayList<TextView> textViews = des.getText();
Iterator<TextView> iter = textViews.iterator();
while(iter.hasNext()){
TextView textView = iter.next();
description.addView(textView);
}
This results in my textviews not wrapping onto new lines, even though it works perfectly fine if I include the TextView directly in the XML file.
It results in this:
Edit:
TextView layout:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/TextViewDescription"
style="#style/AppTheme"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:paddingRight="8dp"
android:text="Loading data..."
android:textSize="#dimen/description_size"
android:layout_weight="1"
android:ellipsize="none"
android:scrollHorizontally="false" />

You probably need to set it to multi line. Try
setInputType (InputType.TYPE_TEXT_FLAG_MULTI_LINE);
If you have other InputType attributes, you'll need to "or" them together.

At this part of your code, you are getting your TextView array:
ArrayList<TextView> textViews = des.getText();
And we don't see how those TextView's are created. But I assume you did not set single_line or max_lines to TextViews.
Try this code while adding your TextViews to your LinearLayout:
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
while (iter.hasNext()) {
TextView textView = iter.next();
description.addView(textView, params);
}
Edit:
Use below layout while creating your TextViews(I've removed some attrs and style.):
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/TextViewDescription"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:paddingRight="8dp"
android:text="Loading data..."
android:textSize="#dimen/description_size"/>
Edit2: Change your layout_width param to wrap_content. Also see updated param at code above. (This worked for me)
<LinearLayout android:id="#+id/LinearLayout_Description"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<!-- Dynamically added TextView here -->
</LinearLayout>

Try using something other than TableLayout. I'm not very experienced with TableLayout but I think it needs the child views to have relatively short and consistent widths.
Instead, try using LinearLayout, like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout_InfoShow"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="#dimen/table_row_padding_bottom" >
<TextView
android:id="#+id/DescriptionTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-light"
android:textSize="#dimen/page_name_size"
android:text="Loading data..." />
<!-- Dynamically added TextView here -->
</LinearLayout>
And add the views with more-or-less the same code you had before. Note I changed the parent view for supporting the adds -- outerLayout.
View view = inflater.inflate(R.layout.description_card, null);
TextView outerView = (TextView) view.findViewById(R.id.LinearLayout_InfoShow);
ArrayList<TextView> textViews = des.getText();
Iterator<TextView> iter = textViews.iterator();
while(iter.hasNext()) {
TextView textView = iter.next();
outerView.addView(textView);
}

Found the reason.
The inflater needed a ViewGroup for the layout params to take effect.
I had to change the way I pass the text through to the iterator but this is basically what needed changing:
TextView textView = (TextView) inflater.inflate(text.getViewID(), description, false);

For the problem...
When you have
<TableLayout>
<TableRow>
<TextView>
</TextView>
</TableRow>
</TableLayout>
to make the text appear without truncation,
add
android:layout_weight="1"
inside the textview
<TextView>
</TextView>

Android: EditText in TableRow does not wrap when added by code

I'm stuck with the following:
Trying to place a left-aligned multiline EditText to the left of a ToggleButton for each row of a table.
Layout XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="right"
android:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<TableLayout
android:id="#+id/tableLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TableRow
android:id="#+id/tableRow2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="right|center_vertical" >
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#00000000"
android:ems="10"
android:focusable="false"
android:focusableInTouchMode="false"
android:inputType="none"
android:text="A very long line that should be wrapped into two or more lines as it doesn't fit on one line" />
<ToggleButton
android:id="#+id/toggleButton3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ToggleButton" />
</TableRow>
</TableLayout>
</LinearLayout>
This produces exactly what I'm looking for (Example: http://s8.postimg.org/6ldgsovr9/before.png).
But then I try to add a new row with this code:
TableLayout tl = (TableLayout)findViewById(R.id.tableLayout1);
TableRow row = new TableRow(this);
row.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
row.setGravity(Gravity.RIGHT | Gravity.CENTER_VERTICAL);
EditText et = new EditText(this);
et.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
TableRow.LayoutParams params = (TableRow.LayoutParams) et.getLayoutParams();
params.height = TableRow.LayoutParams.WRAP_CONTENT;
et.setLayoutParams(params);
et.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE);
et.setBackgroundColor(Color.TRANSPARENT);
et.setText("A very long line that should be wrapped into two ore more lines as it doesn't fit on one line");
row.addView(et);
ToggleButton tb = new ToggleButton (this);
row.addView(tb);
tl.addView(row, new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT));
Which messes up the existing line and the new line does not wrap at all (Example: http://s24.postimg.org/3ty1ne71x/after.png)
What am I missing here?
Thanks!

I face similar issue... Though its late reply, Just posting so it may help somebody...
I solved issue by adding these attributes to TableLayout
android:stretchColumns="0"
android:shrinkColumns="0"
and also set inputType for EditText
android:inputType="textMultiLine"

Try commenting the following line.
//et.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE);

Hope I can help you :D
If you want to set Multline on XML. Add this betwween TextView Tag:
android:maxLines="4"
android:lines="4"
If you want to set it on run time. Use this.
mTextView.setMaxLines(maxlines)
mTextView.setLines(lines)

It looks like the following line solves the display issue:
et.setEms(10);
I don't know why this makes a difference (the font size stays the same) but now the text is aligned correctly.
