Question

I want to swap two button positions when we click on toggle button. I have tried a lot but haven’t got a success. So if anyone knows how to do this please suggest me.
Thanks all.

You could try a sneaky workaround using View.setVisibility(). Start with res/layout/main.xml:

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:orientation="vertical" >

        <Button
            android:id="@+id/switcher"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Switch"
            android:onClick="switchButtons" />
        <Button
            android:id="@+id/buttonA1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button A" />
        <Button
            android:id="@+id/buttonB1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button B" />
        <Button
            android:id="@+id/buttonB2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button B"
            android:visibility="gone" />
        <Button
            android:id="@+id/buttonA2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button A"
            android:visibility="gone" />

</LinearLayout>

And now we have an Activity to put this layout in:

public class Foo extends Activity {

    Button switcher;
    Button A1;
    Button A2;
    Button B1;
    Button B2;
    boolean buttons1AreVisible = true;

    protected void onCreate(Bundle allthethings) {
        super.onCreate(allthethings);
        setContentView(R.layout.main);

        switcher = findViewById(R.id.switcher);
        A1 = findViewById(R.id.buttonA1);
        A2 = findViewById(R.id.buttonA2);
        B1 = findViewById(R.id.buttonB1);
        B2 = findViewById(R.id.buttonB2);
    }

    private void switchButtons() {
        if (buttons1AreVisible) {
            A1.setVisibility(View.GONE);
            B1.setVisibility(View.GONE);
            B2.setVisibility(View.VISIBLE);
            A2.setVisibility(View.VISIBLE);
        } else {
            A1.setVisibility(View.VISIBLE);
            B1.setVisibility(View.VISIBLE);
            B2.setVisibility(View.GONE);
            A2.setVisibility(View.GONE);
        }

        buttons1AreVisible = !buttons1AreVisible;
    }
}

All that remains is for you to assign onClick() methods to the four buttons.
