If I for example have empty layout like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
</LinearLayout>
And some other Layout like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<TextView
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView 1" />
<Button
android:id="@+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button 2" />
<Button
android:id="@+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button 3"
android:layout_weight="1"/>
</LinearLayout>
I would like to add layout2.xml
to layout1.xml
programmatically. I would need to have multiple different version layout2.xml
which I would add when I want. Each one would have different text on TextView
and Button
s.
In case of regular Android View
I would usually do it similarly like this with addView
:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv1 = new TextView(this);
tv1.setText("HELLO");
my_linear_layout.addView(tv1);
Button btn2 = new Button(this);
bt2.setText("WORLD");
my_linear_layout.addView(btn2);
}
How can I do it if I don't have something simple like TextView
or Button
, and if I have my own XML defined View
?
Would it be possible to somehow put all the views inside adapter like for a ListView
and then get it when needed and just call addView
on those View
s?
You can inflate the layout2.xml
file, edit the texts, and add it to the first layout:
public class MyActivity extends Activity {
private ViewGroup mLinearLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout1);
mLinearLayout = (ViewGroup) findViewById(R.id.linear_layout);
addLayout("This is text 1", "This is first button", "This is second Button");
}
private void addLayout(String textViewText, String buttonText1, String buttonText2) {
View layout2 = LayoutInflater.from(this).inflate(R.layout.layout2, mLinearLayout, false);
TextView textView = (TextView) layout2.findViewById(R.id.button1);
Button button1 = (Button) layout2.findViewById(R.id.button2);
Button button2 = (Button) layout2.findViewById(R.id.button3);
textView1.setText(textViewText);
button1.setText(buttonText1);
button2.setText(buttonText2);
mLinearLayout.addView(layout2);
}
}
You may want to change android:layout_height
of the layout2.xml
root view to wrap_content
.
