Add multiple custom views to layout programmatically
Solution 1
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
.
If you are using ViewBinding, here is how it would look like for the addLayout
function :
MyLayoutBinding binding = MyLayoutBinding.inflate(getLayoutInflater(), mLinearLayout, false);
binding.getTextView1().setText(textViewText);
binding.getButton1().setText(buttonText1);
binding.getButton2().setText(buttonText2);
mLinearLayout.addView(binding.getRoot());
Solution 2
layout1.xml
contains ScrollView
as parent layout and main LinearLayout
as child if no row item more screen size ScrollView
handle overflow item with scroll:
layout1.xml
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/my_linear_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
Use LayoutInflater
to add row item to parent LinearLayout
:
private LinearLayout my_linear_layout;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout1);
my_linear_layout = (LinearLayout) findViewById(R.id.my_linear_layout);
for (int i = 1; i <= 5; i++) {
View view = LayoutInflater.from(this).inflate(R.layout.layout2, null);
TextView button1 = (TextView) view.findViewById(R.id.button1);
Button button2 = (Button) view.findViewById(R.id.button2);
TextView button3 = (TextView) view.findViewById(R.id.button3);
button1.setText("HELLO " + i);
button2.setText("HELLO " + i);
button3.setText("HELLO " + i);
my_linear_layout.addView(view);
}
}
Solution 3
Try this method
Add id
to LinearLayout
'layout1.xml':
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/firstlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
</LinearLayout>
In onCreate
:
LinearLayout firstlayout = (LinearLayout) findViewById(R.id.firstlayout);
LinearLayout secondlayoout = (LinearLayout) this.getLayoutInflater().inflate(R.layout.layout2, null); // inflating view from xml
TextView btn1 = (TextView) secondlayoout.findViewById(R.id.button1);
btn1.setText("TEST");
firstlayout.addView(secondlayoout);

If I for example have empty layout like this:
layout1.xml
<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:
layout2.xml
<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
tolayout1.xml
programmatically. I would need to have multiple different versionlayout2.xml
which I would add when I want. Each one would have different text onTextView
andButton
s.In case of regular Android
View
I would usually do it similarly like this withaddView
: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
orButton
, and if I have my own XML definedView
?Would it be possible to somehow put all the views inside adapter like for a
ListView
and then get it when needed and just calladdView
on thoseView
