Tried to align imageview to right.. code crashes. why?
UPDATED: Here is all row im having problem with. I think i failed on determining layouts somewhere here
TableRow tableRow1 = new TableRow(this);
tableRow1.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
tl.addView(tableRow1);
/* textView1 */
TextView textView1 = new TextView(this);
textView1.setLayoutParams(new TableRow.LayoutParams(
LayoutParam
s.MATCH_PARENT, LayoutParams.MATCH_PARENT));
textView1.setText(names);
tableRow1.addView(textView1);
ImageView icon;
icon = new ImageView(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
icon.setLayoutParams(params);
// icon.setLayoutParams(params);
icon.setImageResource(R.drawable.ic_done); //default value
switch (value) {
case "1":
icon.setImageResource(R.drawable.ic_done);
break;
case "0":
icon.setImageResource(R.drawable.ic_bad);
default:
break;
}
System.out.println("value : " + value);
icon.setPadding(densityToPixels(13), 0, 0, 0);
tableRow1.addView(icon);

First you defined the ImageView dynamically like
ImageView icon = new ImageView(this);
then you are trying to get the LayoutParam through icon.getLayoutParams(); which doesn't have any LayoutPram because you haven't set any.
To make it work replace
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)icon.getLayoutParams();
with
TableRow.LayoutParams params = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
icon.setLayoutParams(params);

This produces the layout that i want:
Now i would like to add the above layout and change it to a java way
I hav tried
//top layout
RelativeLayout newlayout = new RelativeLayout(getContext());
LinearLayout belowlayout = new LinearLayout(getContext());
LinearLayout above_part = new LinearLayout(getContext()); //lin with id of above_part
LinearLayout in_above_part_one = new LinearLayout(getContext()); //lin with id of above_part
//layouts properties
belowlayout.setOrientation(LinearLayout.HORIZONTAL);
//setids for the layouts
newlayout.setId(12);
belowlayout.setId(13);
//Button
Button additemsbtn = new Button(getContext());
additemsbtn.setText("Log In");
additemsbtn.setBackgroundColor(Color.BLACK);
//Username input
EditText username = new EditText(getContext());
additemsbtn.setId(int 1);
username.setId(2);
RelativeLayout.LayoutParams buttonDetails = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT,
);
RelativeLayout.LayoutParams usernameDetails = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT
);
//Give rules to position widgets
usernameDetails.addRule(RelativeLayout.ABOVE, additemsbtn.getId());
usernameDetails.addRule(RelativeLayout.CENTER_HORIZONTAL);
usernameDetails.setMargins(0,0,0,50);
buttonDetails.addRule(RelativeLayout.CENTER_HORIZONTAL);
buttonDetails.addRule(RelativeLayout.CENTER_VERTICAL);
Whatever i have started fails since am unable to know how to nest the different linear layouts,
I would probably like guidelines on how to do this nesting programmatically so that i can achieve the same thing generated by the xml file
Little example how it can be done. So, all you need to do is to add inner items to my nested layouts and configure margins/paddings etc. Also added background for better visualization.
RelativeLayout root = (RelativeLayout) findViewById(R.id.root);
Button addButton = new Button(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
addButton.setLayoutParams(params);
addButton.setId(123);
root.addView(addButton);
LinearLayout rootLinearlayout = new LinearLayout(this);
RelativeLayout.LayoutParams linearRootParams = new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
linearRootParams.addRule(RelativeLayout.BELOW, 123);
rootLinearlayout.setBackgroundColor(ContextCompat.getColor(this, R.color.colorAccent));
rootLinearlayout.setLayoutParams(linearRootParams);
// Nested Linears
LinearLayout linearOne = new LinearLayout(this);
LinearLayout linearTwo = new LinearLayout(this);
LinearLayout linearThree = new LinearLayout(this);
LinearLayout.LayoutParams linearParamsWithWeight = new LinearLayout.LayoutParams(
0,
300);
linearParamsWithWeight.weight = 1;
linearOne.setBackgroundColor(ContextCompat.getColor(this, android.R.color.black));
linearTwo.setBackgroundColor(ContextCompat.getColor(this, android.R.color.holo_red_dark));
linearThree.setBackgroundColor(ContextCompat.getColor(this, android.R.color.holo_blue_dark));
linearOne.setLayoutParams(linearParamsWithWeight);
linearTwo.setLayoutParams(linearParamsWithWeight);
linearThree.setLayoutParams(linearParamsWithWeight);
rootLinearlayout.addView(linearOne);
rootLinearlayout.addView(linearTwo);
rootLinearlayout.addView(linearThree);
I have next Layout (TOP: Two Spinner Half: TableLayout Down: Button) , I have filled the TableLayout with WebService with...
"for (int i = 0; i < ljsonArray.length(); i++)"
But when the last record of WebService show in the TableLayout, the button disappeared, what's wrong?
Regards

Your button is actually on the right of your tableLayout.
Change the orientation of the linearlayout to Vertical instead of horizontal.
Moreover the buttonView should be part of the scrollview if you want to see it at the end of the scrollview.
You can also nested all your xml in a Relative layout et add the attribute "android:layout_alignParentBottom="true" to the button and the button will always be visible.
Hope this helps.

It works for me when I add rows directly in xml.
I using LinearLayout as a table that need to contain 3 column.
I need to feel up the row an i don't know how to do it from the code in run time.
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout"
android:paddingTop="4dip"
android:paddingBottom="6dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView android:id="#+id/Cell1"
android:layout_width="50dip"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/Cell2"
android:layout_width="70dip"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<TextView android:id="#+id/Cell3"
android:layout_width="60dip"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>
This is the code that produces layout equivalent to what you have declared in your .xml
You could put it somewhere in your activity (so this refers to your activity)
LinearLayout row = new LinearLayout(this);
row.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
row.setPadding(0, 4, 0, 6);
row.setOrientation(LinearLayout.HORIZONTAL);
// creating and setting the cells now
// cell 1
TextView cell1 = new TextView(this);
// convert dip into pixels for LayoutParams constructor
// as it only understands px
int widthPix1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
50, getResources().getDisplayMetrics());
row.addView(cell1, new LinearLayout.LayoutParams(
widthPix1, LinearLayout.LayoutParams.WRAP_CONTENT));
// cell 2
TextView cell2 = new TextView(this);
int widthPix2 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
70, getResources().getDisplayMetrics());
row.addView(cell2, new LinearLayout.LayoutParams(
widthPix2, LinearLayout.LayoutParams.WRAP_CONTENT, 1));
// cell 3
TextView cell3 = new TextView(this);
int widthPix3 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
60, getResources().getDisplayMetrics());
row.addView(cell3, new LinearLayout.LayoutParams(
widthPix3, LinearLayout.LayoutParams.WRAP_CONTENT, 1));
As you can see the amount of code is significantly bigger than when your layout is in .xml and you simply inflate with
LinearLayout row = (LinearLayout) inflater.inflate(R.layout.row, null);
And I can hardly imagine a situation when you want to do it the way you asked for.
Anyways, enjoy.
My advice if I got you right:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout"
android:paddingTop="4dip"
android:paddingBottom="6dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView android:id="#+id/Cell1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5"/>
<TextView android:id="#+id/Cell2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="7"/>
<TextView android:id="#+id/Cell3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="6"/>
</LinearLayout>
I'm trying to build a part of a Android View Programmatically, but unfortunately I'm having some problems with the RelativeLayout. it makes my Elements overlay on eachother
This is my Code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.insertnew_layout);
LinearLayout ll = (LinearLayout) findViewById(R.id.container);
ll.setOrientation(LinearLayout.VERTICAL);
TableLayout tl = new TableLayout(this);
tl.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
// fill content
for (int i = 0; i < 3; i++) {
TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
RelativeLayout rl = new RelativeLayout(this);
rl.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
TextView score = new TextView(this);
score.setText(""+i);
RelativeLayout.LayoutParams lpScore = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
lpScore.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
score.setLayoutParams(lpScore);
TextView description = new TextView(this);
description.setText("this is my description");
RelativeLayout.LayoutParams lpDescription = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
lpDescription.addRule(RelativeLayout.RIGHT_OF, score.getId());
description.setLayoutParams(lpDescription);
CheckBox checkbox = new CheckBox(this);
RelativeLayout.LayoutParams lpCheckbox = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
lpCheckbox.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
checkbox.setLayoutParams(lpCheckbox);
rl.addView(score);
rl.addView(description);
rl.addView(checkbox);
tl.addView(rl);
}
ll.addView(tl);
This is what it looks like:
As you can see, the "description" is on top of of the "score".
Here is the same code in xml:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/tableLayoutTextEntry" >
<TableRow
android:id="#+id/tableRowTextEntry"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/score"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="score" />
<TextView
android:id="#+id/description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/score"
android:text="description" />
<CheckBox
android:id="#+id/checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="select" />
</RelativeLayout>
</TableRow>
</TableLayout>
And here is what it looks like in xml:
As you can see, in xml, the toRightOf-command works as expected - the description is to the right of the score
How is that possible? Shouldnt the line
lpDescription.addRule(RelativeLayout.RIGHT_OF, score.getId());
do the same thing?
At the moment you are calling it, score.getId() will return -1 (invalid), because it has not been added yet to the screen with the whole layout processed.
You will have to set the id manually with setId() before calling getId() and it should all work fine.
I'm trying to correlate how the Android XML looks versus creating it programmatically and I'm failing miserably. I've read several references stating that the type for the LayoutParams for the View must be equal to those of the parent, but I'm just not grokking it.
Given the following XML, how would I re-create this programmatically?
<TableRow
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_gravity="center_vertical"
>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_gravity="center_vertical"
android:paddingTop="3dp"
android:orientation="vertical"
>
<EditText
android:padding="2dp"
android:layout_width="100dp"
android:layout_height="35dp"
android:layout_column="0"
android:layout_weight="1"
android:layout_gravity="center_vertical"
android:textSize="15dp"
android:numeric="integer"
/>
</LinearLayout>
<LinearLayout
android:layout_height="35dp"
android:layout_width="fill_parent"
android:layout_weight="1"
android:layout_gravity="center_vertical"
android:padding="2dp"
android:orientation="vertical"
>
<CheckBox android:text="Check1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="10sp"
android:background="#drawable/checkbox_background"
android:button="#drawable/checkbox"
android:textColor="#color/Gray"
/>
<CheckBox android:text="Check2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="10sp"
android:background="#drawable/checkbox_background"
android:button="#drawable/checkbox"
android:textColor="#color/Gray"
/>
</LinearLayout>
Here's what I've tried:
// Get the TableLayout
TableLayout tl = (TableLayout)findViewById(R.id.score_table);
LayoutParams lp;
TableRow.LayoutParams tp;
// Create a TableRow and give it an ID
TableRow tr = new TableRow(this);
tr.setId(100);
tr.setLayoutParams(new TableRow.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
LinearLayout ll0_1 = new LinearLayout(this);
// If the layout params of the child should be of
// the type of the parent this should be
// TableRow.LayoutParams?
tp = (TableRow.LayoutParams)tr.getLayoutParams();
tp.height = TableRow.LayoutParams.WRAP_CONTENT;
tp.width = TableRow.LayoutParams.FILL_PARENT;
tp.gravity = Gravity.CENTER_VERTICAL;
// TableRow.LayoutParams has no padding so this
// gets set on the LinearLayout?
ll0_1.setPadding(0,3,0,0);
ll0_1.setLayoutParams(tp);
tr.addView(ll0_1);
EditText et0 = new EditText(this);
et0.setId(100);
et0.setInputType(InputType.TYPE_CLASS_NUMBER);
// Same as above; LP set to type of parent
lp = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT, 1f);
lp.height = 35;
lp.width = 100;
// Same as above; the parent's type doesn't have
// these attributes
et0.setTextSize(TypedValue.COMPLEX_UNIT_SP, 15);
et0.setPadding(0, 3, 0, 0);
et0.setLayoutParams(lp);
ll0_1.addView(et0);
LinearLayout ll0_2 = new LinearLayout(this);
ll0_2.setOrientation(LinearLayout.VERTICAL);
tr.addView(ll0_2);
CheckBox cb0_1 = new CheckBox(this);
cb0_1.setTextSize(10f);
cb0_1.setTextColor(Color.GRAY);
cb0_1.setBackgroundResource(R.drawable.checkbox_background);
cb0_1.setButtonDrawable(R.drawable.checkbox);
cb0_1.setText("Nil");
ll0_2.addView(cb0_1);
CheckBox cb0_2 = new CheckBox(this);
cb0_2.setTextSize(10f);
cb0_2.setTextColor(Color.GRAY);
cb0_2.setBackgroundResource(R.drawable.checkbox_background);
cb0_2.setButtonDrawable(R.drawable.checkbox);
cb0_2.setText("10fer");
ll0_2.addView(cb0_2);
// Duplicate code removed for brevity
//...
// Add the TableRow to the TableLayout
tl.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
There is no error, but it does not match the XML. Instead, it looks like this:
The first one is from the XML, the second one is my attempt at reproducing it programmatically.
LayoutInflater is the easiest way :
public View myView(){
View v;
LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.myview, null);
TextView text1 = (TextView) v.findViewById(R.id.dolphinTitle);
Button btn1 = (Button) v.findViewById(R.id.dolphinMinusButton);
TextView text2 = (TextView) v.findViewById(R.id. dolphinValue);
Button btn2 = (Button) v.findViewById(R.id. dolphinPlusButton);
return v;
}
