如何在多个文本视图中选择Android上的所有文本？

<TextView
    android:id="@+id/textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Selectable Text"
    android:textIsSelectable="true" />

TextView textView = findViewById(R.id.textView);
textView.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
    @Override
    public boolean onCreateActionMode(ActionMode mode, Menu menu) {
        // 创建ActionMode菜单
        getMenuInflater().inflate(R.menu.context_menu, menu);
        return true;
    }

    @Override
    public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
        // 准备ActionMode菜单
        return false;
    }

    @Override
    public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
        // 处理ActionMode菜单项的点击事件
        switch (item.getItemId()) {
            case R.id.menu_item_copy:
                // 执行复制操作
                textView.onTextContextMenuItem(android.R.id.copy);
                mode.finish(); // 关闭ActionMode
                return true;
            default:
                return false;
        }
    }

    @Override
    public void onDestroyActionMode(ActionMode mode) {
        // 销毁ActionMode
    }
});

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/menu_item_copy"
        android:title="Copy"
        android:icon="@android:drawable/ic_menu_copy"
        android:showAsAction="always" />
</menu>
