I hope question title gives you a good description of the problem.
I want to create this XML, but programatically (please don't suggest not doing it programmatically ^_^ )
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:padding="10dip"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dip"
android:text="Messages:"/>
<EditText android:id="@+id/messageHistory"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="false"
android:layout_weight="1"
android:editable="false"
android:gravity="top"
android:scrollbars="vertical"
android:scrollbarSize="10px"
/>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="4">
<EditText android:id="@+id/message"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="top"
android:layout_weight="1"
/>
<Button android:id="@+id/sendMessageButton"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="4"
android:text="Send"/>
</LinearLayout>
As you can see, there are two LinearLayout's, one embedded in the other. I need to reproduce this and then add it to a ViewFlipper.
This is what I have so far:
LinearLayout l1 = new LinearLayout(this);
LinearLayout l2 = new LinearLayout(this);
Button btn=new Button(this);
EditText messageHistory = new EditText(this);
EditText newMessage = new EditText(this);
TextView windowTitle = new TextView(this);
btn.setText("Send");
btn.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 4f));
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getApplicationContext(), "Clicked send in child index: "+ flipper.getDisplayedChild(), Toast.LENGTH_SHORT).show();
}
});
windowTitle.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
windowTitle.setPadding(0, 5, 0, 10);
windowTitle.setText("Chat with: ");
messageHistory.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
messageHistory.setGravity(Gravity.TOP);
messageHistory.setMovementMethod(new ScrollingMovementMethod());
messageHistory.setClickable(false);
messageHistory.setFocusable(false);
messageHistory.setPadding(0, 0, 0, 5);
newMessage.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 1f));
newMessage.setGravity(Gravity.TOP);
newMessage.setMovementMethod(new ScrollingMovementMethod());
newMessage.requestFocus();
l1.setOrientation(LinearLayout.VERTICAL);
l1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
l2.setOrientation(LinearLayout.HORIZONTAL);
l2.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
l1.addView(windowTitle);
l1.addView(messageHistory);
l2.addView(newMessage);
l2.addView(btn);
l1.addView(l2);
flipper.addView(l1);
Where flipper is defined as:
ViewFlipper flipper = (ViewFlipper) findViewById(R.id.viewflip);
Without a problem, I can see "l1" in the window when it loads up, but l2 is no where to be found. Did I mess up with LayoutParams? Can I use addView to add a LinearLayout?
I think you forgot to set layout weight (only my opinion though, could be wrong). because you are adding more views with layout-height set to FILL_PARENT
