当我单击活动2的按钮时，我想向活动1添加一个容器

Button button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent(Activity2.this, Activity1.class);
        intent.putExtra("addContainer", true);
        startActivity(intent);
    }
});

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity1);

    // 接收来自活动2的Intent
    Intent intent = getIntent();
    boolean addContainer = intent.getBooleanExtra("addContainer", false);

    // 根据传递的数据添加容器
    if (addContainer) {
        LinearLayout parentLayout = findViewById(R.id.parent_layout);
        LinearLayout container = new LinearLayout(this);
        container.setLayoutParams(new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT,
                LinearLayout.LayoutParams.WRAP_CONTENT));
        container.setOrientation(LinearLayout.VERTICAL);
        container.setBackgroundColor(Color.GRAY);
        parentLayout.addView(container);
    }
}
