I am trying to display a simple ImageView in a TableRow but for some reason it won't display. If I add another control to another row the imageView does display, so it seems like it is just not forcing the size correctly. My xml is as follows:
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:background="#4B088A"
android:id="#+id/ImageTable">
<TableRow android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:id="#+id/ImageTableRow"/>
</TableLayout>
The code that I am using to add the ImageView is:
TableLayout tableLayout = (TableLayout) findViewById(R.id.ImageTable);
TableRow tr = new TableRow(this);
TableRow.LayoutParams lp = new
TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT ,TableRow.LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
m_imageView = new MyImageView(getApplicationContext());
m_imageView.setBackgroundColor(Color.GRAY);
m_imageView.setImageBitmap(charty);
tr.addView(m_imageView);
tableLayout.addView(tr);
try this code
write your xml "activity_main" as
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TableLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_action_search" />
</TableRow>
</TableLayout>
</LinearLayout>
ic_action_search is your image in drawable folder and write main activity as
public class MainActivity extends Activity
{
ImageView image;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}

My goal is to dynamically add a toggleButton to a frameLayout (which has it's own weight), but have the button be half the width of the frameLayout. I am able to create what I want in XML, but I'm having trouble trying to make this work programmatically.
Here's my XML:
<?xml version="1.0" encoding="utf-8"?>

<FrameLayout
android:id="#+id/column_1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<View
android:layout_width="match_parent"
android:layout_height="60dp"
android:background="#android:color/background_dark" />

</LinearLayout>
Please pay particular attention to the LinearLayout with the id: buttonLayoutWrapper and it's child ToggleButton as those are what I need to add dynamically. For simplicity sake I'm only showing one column, but would repeat this for 7 more.
I tried creating a separate class that Extends LinearLayout and adds the ToggleButton thinking that I could get the weight that way, but no luck.
No matter what I do, I can't seem to get the ToggleButton to obey the layout_weight.
Below is a sample of trying to do this programmatically:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FrameLayout frameLayout = (FrameLayout) findViewById(R.id.column_1);
ToggleButton toggleButton = new ToggleButton(this);
LinearLayout.LayoutParams layoutWrapper = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 360, .5f);
toggleButton.setChecked(true);
toggleButton.setText("");
toggleButton.setTextOn("");
toggleButton.setTextOff("");
toggleButton.setLayoutParams(layoutWrapper);
frameLayout.addView(toggleButton);
}
It seems that I need to have a parent LinearLayout that sets weightSum for the layout weight to work in the XML version. However, I can't seem to figure out how to add a LinearLayout parent to this that can then be added to the FrameLayout without getting a strange:
cannot cast LinearLayout to FrameLayout
error when compiling.
Rewrite
Try the following. It adds the ToggleButton to the LinearLayout then adds the LinearLayout to the FrameLayout. I think it is what you are looking for. (Comment out the LinearLayout and ToggleButton in the XML so you can see this work.)
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
final float dpToPx = getResources().getDisplayMetrics().density;
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final LinearLayout linearLayout = new LinearLayout(this);
final FrameLayout.LayoutParams frameLP =
new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
FrameLayout.LayoutParams.MATCH_PARENT);
linearLayout.setLayoutParams(frameLP);
linearLayout.setId(View.generateViewId()); // API 17+ needed
linearLayout.setWeightSum(2.0f);
final ToggleButton toggleButton = new ToggleButton(this);
final LinearLayout.LayoutParams linearLP =
new LinearLayout.LayoutParams(0, (int) (360 * dpToPx), 1.0f);
toggleButton.setLayoutParams(linearLP);
toggleButton.setChecked(true);
toggleButton.setText("");
toggleButton.setTextOn("");
toggleButton.setTextOff("");
linearLayout.addView(toggleButton);
final FrameLayout frameLayout = (FrameLayout) findViewById(R.id.column_1);
frameLayout.addView(linearLayout);
}
}
I have a little bit problem that displaying list data to TextView in Android. My scenario is I have a TableLayout with Default One TableRow. Inside table row, I has been created new LinearLayout. Then, Four TextView created inside LinearLayout. I adding some default value to this textview. My default value is
1, 2014-02-05, S02, 20
Here my code snippet for above scenari0.
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#color/sync_history_table_color"
android:id="#+id/history_table"
android:orientation="vertical"
>
<TableRow
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:paddingTop="1dp"
android:id="#+id/row_start">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="30dp" android:id="#+id/row_linear" android:layout_weight="1"
android:background="#color/isp_home_color">

</TableLayout>
Actually, I want to create dynamically TableRow, LinearLayout and TextView. Then, I put the list result to add these. The list result come from sqlite db. But, I can't get what I want. Here my code for looping the list and display the result. But, I got my some default value. Please pointing to me how can I get this. Thanks.
Here snippet for display list.
public void displayHistory(){
List<IspHistoryListObject> historyList = sqlaccess.getAllItems();
TableLayout showRow = (TableLayout) findViewById(R.id.history_table);
int count = 0;
for(IspHistoryListObject hl : historyList) {
count++;
TableRow tr = new TableRow(this);
LinearLayout ll = new LinearLayout(this);
ll.setLayoutParams(new LinearLayout.LayoutParams(50,30));
TextView tv_sync_no = new TextView(this);
TextView tv_sync_date = new TextView(this);
TextView tv_sync_orderid = new TextView(this);
TextView tv_sync_qty = new TextView(this);
tv_sync_no.setText(String.valueOf(count));
tv_sync_date.setText(hl.getSyncDate().substring(0,10));
tv_sync_orderid.setText(hl.getSyncOrderIdRef());
tv_sync_qty.setText(String.valueOf(hl.getQty()));
ll.addView(tv_sync_no);
ll.addView(tv_sync_date);
ll.addView(tv_sync_orderid);
ll.addView(tv_sync_qty);
tr.addView(ll);
showRow.addView(tr);
}
}
try this way here I gave sample or demo code you have to modify as per your requirement and still have problem let me know
main layout
1. table.xml
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tableLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp"
android:orientation="vertical">
</TableLayout>
table row layout
2. table_item.xml
<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"

activity class
3. Activity
public class MyActivity extends Activity {
private TableLayout tableLayout;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.table);
tableLayout=(TableLayout)findViewById(R.id.tableLayout);
for (int i=0;i<5;i++){
View tableRow = LayoutInflater.from(this).inflate(R.layout.table_item,null,false);
TextView history_display_no = (TextView) tableRow.findViewById(R.id.history_display_no);
TextView history_display_date = (TextView) tableRow.findViewById(R.id.history_display_date);
TextView history_display_orderid = (TextView) tableRow.findViewById(R.id.history_display_orderid);
TextView history_display_quantity = (TextView) tableRow.findViewById(R.id.history_display_quantity);
history_display_no.setText(""+(i+1));
history_display_date.setText("2014-02-05");
history_display_orderid.setText("S0"+(i+1));
history_display_quantity.setText(""+(20+(i+1)));
tableLayout.addView(tableRow);
}
}
}
check out context hierachy
for(IspHistoryListObject hl : historyList) {
count++;
TableRow tr = new TableRow(showRow.getContext());
LinearLayout ll = new LinearLayout(tr.getContext());
ll.setLayoutParams(new LinearLayout.LayoutParams(50,30));
TextView tv_sync_no = new TextView(ll.getContext());
TextView tv_sync_date = new TextView(ll.getContext());
TextView tv_sync_orderid = new TextView(ll.getContext());
TextView tv_sync_qty = new TextView(ll.getContext());
tv_sync_no.setText(String.valueOf(count));
tv_sync_date.setText(hl.getSyncDate().substring(0,10));
tv_sync_orderid.setText(hl.getSyncOrderIdRef());
tv_sync_qty.setText(String.valueOf(hl.getQty()));
ll.addView(tv_sync_no);
ll.addView(tv_sync_date);
ll.addView(tv_sync_orderid);
ll.addView(tv_sync_qty);
tr.addView(ll);
showRow.addView(tr);
}
With listview you can easily do this:
ActivityMain.java
ListView lst = (ListView) findViewById(R.id.listView);
View header = getLayoutInflater().inflate(R.layout.list_header, null);
lst.addHeaderView(header);
lst.setAdapter(new CustomerListAdapter(this,4));
list_header.xml is header layout
I want to develop an app like this. Which is exactly like android gallery.
So I tried with HorizontalScrollView. But still I am facing some problems
Here is my layout.
<ImageView
android:id="#+id/main"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/hScrollView"/>
<HorizontalScrollView
android:id="#+id/hScrollView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<LinearLayout
android:id="#+id/linearLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
and here is my code
LinearLayout image;
ImageView main;
ImageView[] iv=new ImageView[images.length];
int i;
and in Activity,
for(i=0;i<images.length;i++)
{
iv[i]=new ImageView(this);
LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
iv[i].setLayoutParams(lparams);
iv[i].setImageResource(images[i]);
iv[i].setTag(images[i]);
image.addView(iv[i]);
iv[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
main.setImageResource((Integer) iv[i].getTag());
}
});
But it is always giving me ArrayIndexOutOfBoundException. I know Value of i is getting updated for each iteration.
So What am I supposed to do? Any alternative ways are appreciable.
I am using api level 18 so Gallery won't work.
Try this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/hScrollView"
android:background="#drawable/ic_launcher" />
<HorizontalScrollView
android:id="#+id/hScrollView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<LinearLayout
android:id="#+id/linearLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
</RelativeLayout>
In Activity class:
int[] drawable = { R.drawable.background, R.drawable.forground,
R.drawable.ic_launcher, R.drawable.ic_launcher,
R.drawable.ic_launcher, R.drawable.ic_launcher };
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
centerImageView = (ImageView) findViewById(R.id.imageView);
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linearLayout);
for (int i = 0; i < drawable.length; i++) {
LinearLayout.LayoutParams lparams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
ImageView view = new ImageView(this);
view.setLayoutParams(lparams);
view.setId(i);
view.setImageResource(drawable[i]);
linearLayout.addView(view);
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
centerImageView.setImageResource(drawable[v.getId()]);
}
});
}
}
Hope will help you:)
you can use like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

Please note: android.widget.Gallery is no longer supported. Other horizontally scrolling widgets include HorizontalScrollView and ViewPager from the support library.
As per your requirement the HorizontalScrollView is more suitable. Check out the below tutorial which will help you in implementation.
Implement HorizontalScrollView like GalleryView
I wish to create a custom layout out for my sample application. Previously i used the xml layout for User interface, but now i wish to create the application using custom (without using xml layout). I used the below code in my xml, but i change this xml layout to custom code i can't implement (i don't have knowledge how to do this). How can i write this layout code in my Activity?. Any one could you please help me to solve this. Thanks in advance.

As you want to create layout at run-time, you can do this way:
RelativeLayout layout1 = new RelativeLayout(this);
ImageView imgView1 = new imgView1(this);
layout1.addView(imgView1); // added ImageView into the RelativeLayout
do this kind of process for creating and adding widgets.
LinearLayout ll1,ll2;
ScrollView sv = new ScrollView(this);
RelativeLayout rl1,rl2;
WebView wv1,wv2;
ImageView iv1,iv2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
int LHeightWrap = LinearLayout.LayoutParams.WRAP_CONTENT;
int LWidthWrap = LinearLayout.LayoutParams.WRAP_CONTENT;
int LHeightFill = LinearLayout.LayoutParams.FILL_PARENT;
int LWidthFill = LinearLayout.LayoutParams.FILL_PARENT;
int RHeightWrap = RelativeLayout.LayoutParams.WRAP_CONTENT;
int RWidthWrap = RelativeLayout.LayoutParams.WRAP_CONTENT;
int RHeightFill = RelativeLayout.LayoutParams.FILL_PARENT;
int RWidthFill = RelativeLayout.LayoutParams.FILL_PARENT;
wv1 = new WebView(this);
iv1 = new ImageView(this);
rl1.addView(wv1,RWidthWrap,RHeightWrap);
rl1.addView(iv1,RWidthWrap,RHeightWrap);
wv2 = new WebView(this);
iv2 = new ImageView(this);
rl2.addView(wv2,RWidthWrap,RHeightWrap);
rl2.addView(iv2,RWidthWrap,RHeightWrap);
ll2.addView(rl1);
ll2.addView(rl2);
sv.addView(ll2);
ll1.addView(ll2);
You can do somthing like this. You can also set properties of any component using native code.
I have an tableview which i want to scroll, because the data is not shown complete.
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="0,1,2,3,4"
android:id="#+id/maintable" >
</TableLayout>
this is my tablelayout, and if i wrap it in an <ScrollView> </Scrollview> the Application crashs if i open the activity. How to do that?
You should really put the code you tried that crashed your application and the reason for your crash. There's no valuable information in your original post.
Ehhh... did you try something as simple as this? Example .xml that I use a few places:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableLayout android:id="#+id/score_table"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableRow android:id="#+id/header"/>
</TableLayout>
</ScrollView>
Works absolutely fine for me. You don't have to include the TableRow if you have no use for it, obviously.
Create your rows dynamically
Here I am putting a small example,
main.xml
<Button android:id="#+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Add row"></Button>
<ScrollView android:id="#+id/ScrollView01" android:layout_width="wrap_content" android:layout_height="wrap_content">
<TableLayout android:id="#+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:stretchColumns="0">
<TableRow android:id="#+id/TableRow01" android:layout_width="wrap_content" android:layout_height="wrap_content">
<TextView android:id="#+id/TextView01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="textfield 1-1"></TextView>
<CheckBox android:id="#+id/CheckBox01" android:layout_width="wrap_content" android:layout_height="wrap_content"></CheckBox>
</TableRow>
</TableLayout>
</ScrollView>
Activity is
public class tablelayout extends Activity implements OnClickListener {
/** Called when the activity is first created. */
//initialize a button and a counter
Button btn;
int counter = 0;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setup the layout
setContentView(R.layout.main);
// add a click-listener on the button
btn = (Button) findViewById(R.id.Button01);
btn.setOnClickListener(this);
}
// run when the button is clicked
public void onClick(View view) {
// get a reference for the TableLayout
TableLayout table = (TableLayout) findViewById(R.id.TableLayout01);
// create a new TableRow
TableRow row = new TableRow(this);
// count the counter up by one
counter++;
// create a new TextView
TextView t = new TextView(this);
// set the text to "text xx"
t.setText("text " + counter);
// create a CheckBox
CheckBox c = new CheckBox(this);
// add the TextView and the CheckBox to the new TableRow
row.addView(t);
row.addView(c);
// add the TableRow to the TableLayout
table.addView(row,new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
}
You can create your table row, when in your code require. I assumed it is on button click.
Hope this will help.
And here one more example.
