如何在android中做一个完美的正方形？

<!-- square_layout.xml -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <View
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

// 在Activity或Fragment中的代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    LinearLayout containerLayout = findViewById(R.id.container_layout);
    int screenWidth = getResources().getDisplayMetrics().widthPixels;
    int screenHeight = getResources().getDisplayMetrics().heightPixels;
    int squareSize = Math.min(screenWidth, screenHeight);

    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(squareSize, squareSize);
    containerLayout.setLayoutParams(layoutParams);
}
