将contentDescription添加到TextView列表中

Question

我正在尝试弄清楚如何将一个contentDescription添加到ListView，因为它正在填充。我看一个答案，但不知道如何实现它。这是我的代码：

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    drawerLayout=(DrawerLayout) findViewById(R.id.drawerLayout);
    drawerListener = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.ic_drawer, 
            R.string.drawer_open, R.string.drawer_close){

        public void onDrawerOpen(View drawerView){

            super.onDrawerOpened(drawerView);
        }

        public void onDrawerClosed(View drawerView){

            super.onDrawerClosed(drawerView);
        }
    };

    drawerLayout.setDrawerListener(drawerListener);
    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    planets=getResources().getStringArray(R.array.planets);  //get planets array
    listView=(ListView) findViewById(R.id.drawerList);

    //Set ArrayAdapter
    listView.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, planets ));

    //set onClickListener for array
    listView.setOnItemClickListener(this);
}

感谢;

Answer 1

ArrayAdapter没有这样做。你必须扩展它，如下：

用listView.setAdapter(...代替：

listView.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, planets ){

    @Override
    public View getView (int position, View convertView, ViewGroup parent) {
       View v = super.getView(position, convertView, parent);
       v.setContentDescription(... value ...);
       return v;
    }

});
