Add multiple custom views to layout programmatically

Question

If I for example have empty layout like this:

layout1.xml

Answer 1

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);

Answer 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);
    }
}

Answer 3

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.
