Question

所以我正在使用Android应用程序，我正在使用来自数据库的元素填充ListActivity，然后使用onListItemClick移动到基于用户选择的行传递信息的新活动。唯一的问题似乎是我如何做意图，导致应用程序崩溃。

protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        Movie m = (Movie) this.getListAdapter().getItem(position);
        long selection = m.getId();
        //Toast.makeText(this, "You have chosen the movie: " + " " + selection, Toast.LENGTH_LONG).show();

        Intent viewTrailer = new Intent(MainActivity.this, ViewTrailer.class);

        viewTrailer.putExtra("movieId", selection);
        startActivity(viewTrailer);
    }

Toast只是用于调试目的。应该发生的是，意图根据他们的选择获得额外的Id并将其传递给下一个活动。选择得到正确的值，但程序在

崩溃

    startActivity(viewTrailer)

行，我收到一条错误说明：源附件不包含文件instrumentation.class的源。我怀疑这个问题是我的来源，看看我是如何使用其他只是编码错误的文件来获取这些文件的。

此外，我已更新我的清单以包含新活动。这是日志猫

到目前为止，viewTrailer并没有太多东西（试图在我做任何事之前让它运行）

public class ViewTrailer extends Activity 
{

    private TextView movieNumber;

    public void onCreate(Bundle savedInstanceState) 
    {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_view_trailer);

//       movieNumber = (TextView) findViewById(R.id.movieNumber);
//       
//       long movieId;
//       
//       Bundle nameBundle = new Bundle();
//          nameBundle = getIntent().getExtras();
//          movieId = nameBundle.getLong("movieId");
//          
//      movieNumber.setText(String.valueOf(movieId));


    }

}

无论是否有评论都尝试过，但两者都会崩溃。

将意图从ListActivity传递给Activity
