Move between layouts in Xamarin.Android-CodePudding

I'm developing an app in Xamarin Android. I want to use a button and then move to the next layout (I have 3 layouts). I'm able to move from layout1 to layout2 but not from layout 2 to layout 3.

LayoutOne

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
    android:background="#1f1e1e"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:orientation="vertical">

    <Button
        android:text="One"
        android:clickable="true"
        android:id="@ id/btnOne"
        android:textSize="16sp"
        android:layout_width="wrap_content"
        android:backgroundTint="#484848"
        android:layout_marginTop="3dp"
        android:layout_gravity="center_horizontal"
        android:layout_height="wrap_content"/>

 </LinearLayout>

//////////////////////////////////

protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        Xamarin.Essentials.Platform.Init(this, savedInstanceState);
        SetContentView(Resource.Layout.LayoutOne);

        Button btnOne = FindViewById<Button>(Resource.Id.btnOne);
        btnOne.Click  = btnOne_Click;
    }
private void btnOne_Click(object Sender, EventArgs e)
    {
       SetContentView(Resource.Layout.LayoutTwo);
    }

LayoutTwo

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
    android:background="#1f1e1e"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:orientation="vertical">

    <Button
        android:text="Two"
        android:clickable="true"
        android:id="@ id/btnTwo"
        android:textSize="16sp"
        android:layout_width="wrap_content"
        android:backgroundTint="#484848"
        android:layout_marginTop="3dp"
        android:layout_gravity="center_horizontal"
        android:layout_height="wrap_content"/>

 </LinearLayout>

//////////////////////////////////

protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        Xamarin.Essentials.Platform.Init(this, savedInstanceState);
        SetContentView(Resource.Layout.LayoutTwo);

        Button btnTwo = FindViewById<Button>(Resource.Id.btnTwo);
        btnTwo.Click  = btnTwo_Click;
    }
private void btnTwo_Click(object Sender, EventArgs e)
    {
       SetContentView(Resource.Layout.LayoutThree);
    }

LayoutThree

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
    android:background="#1f1e1e"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:orientation="vertical">

    <TextView
        android:textSize="16sp"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="This is Layout3"
        android:layout_gravity="center_horizontal"
        android:textColor="@android:color/white"/>

 </LinearLayout>

There is no errors and the app runs. I run it through my phone using usb debugging.

CodePudding user response：

If you want to navigate between three different layouts,a common method is to create three different activities and set the three layouts for them. For example, FirstActivity loads LayoutOne ,SecondActivity loads LayoutTwo and ThirdActivity loads LayoutThree , after that we can use Intent to navigate between them.

Please refer to the following code:

FirstActivity.cs

public class FirstActivity : AppCompatActivity
{
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        Xamarin.Essentials.Platform.Init(this, savedInstanceState);
        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.LayoutOne);

        Button btnOne = FindViewById<Button>(Resource.Id.btnOne);
        btnOne.Click  = BtnOne_Click;
    }

    private void BtnOne_Click(object sender, System.EventArgs e)
    {
        // SetContentView(Resource.Layout.LayoutTwo);

        Intent intent = new Intent(this,typeof(SecondActivity));

        StartActivity(intent);
    }
}

SecondActivity.cs

public class SecondActivity : Activity
{
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        SetContentView(Resource.Layout.LayoutTwo);

        Button btnTwo = FindViewById<Button>(Resource.Id.btnTwo);
        btnTwo.Click  = btnTwo_Click;


    }

    private void btnTwo_Click(object sender, EventArgs e)
    {
        //SetContentView(Resource.Layout.LayoutThree);

        Intent intent = new Intent(this,typeof(ThirdActivity));
        StartActivity(intent);
    }
}

ThirdActivity.cs

public class ThirdActivity : Activity
{
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);

        // Create your application here

       SetContentView(Resource.Layout.LayoutThree);
    }
}
