Here is an example of how to create a custom UI layout using System UI:
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class CustomUILayout extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.custom_ui_layout);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(CustomUILayout.this, "Button clicked!", Toast.LENGTH_SHORT).show();
}
});
TextView textView = (TextView) findViewById(R.id.text_view);
textView.setText("Hello, World!");
}
}This code example creates a custom UI layout with a button and a text view, and demonstrates how to use the System UI to create a custom UI layout.
