在由Arrayadapter制作的listView中执行setOnItemClickListener [关闭]

Question

请帮帮我，我想在点击 listView 的“关于我们”、“更多来自我们”时显示其他活动，我该怎么做？

   ArrayList<Word> words = new ArrayList<Word>();

    words.add(new Word("About Us", R.id.main_images));
    words.add(new Word("More From Us", R.id.main_images));

    WordAdapter adapter = new WordAdapter(this, words);

    ListView listView = findViewById(R.id.list);

    listView.setAdapter(adapter);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            //what should I write here, so I can go other when clicked in listview
        }
    });

Answer 1

您需要创建一个intent 来执行此操作。

Answer 2

你可以像这样在onItemClick上启动一个新的Activity

 listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
          Word word = words.get(i); // it's the selected word
          Intent intent = new Intent(CurrentActivity.this, DetailsActivity.class);
          intent.putExtra("word", word);
          startActivity(intent);
        }
    });

让你的Word类实现Serializable/Parcelable，这样只有你可以发送它并在另一个Activity类中提取。

在DetailsActivity（或您为第二个Activity 起的任何名称）中，您可以在OnCreate 方法中从extra like 中提取所选单词。

Word word = (Word)(getIntent().getSerializableExtra("word"));
// Work on Word

在你的onItemClick：

Switch(i){
 case 0:
    // "About Us" is the first item in your list(position 0) and you can call it here, like
    startActivity(new Intent(this,AboutUsActivity.class))
    break;
case 1:
    // "More From Us" is the second item in your list(position 1) and you can call it here, like
    startActivity(new Intent(this,MoreAboutUs.class))
    break;

}
