从选定的ListViewItem文本填充TextView

我想在每次单击列表视图中的任何文本时在新活动中的TextView上调用setText。例如，如果我点击包含“Android”的listView中的项目，我希望单词“Android”出现在新的活动中。从选定的ListViewItem文本填充TextView

查找下面的代码：

public class ThirdMainActivity extends ActionBarActivity { 

    ListView lvCourses; 
    String[] courses = { "Android", "HTML 5", "J2SE", "JavaScript", "MySQL", "PHP", "CSS", "JQuery", "C#"}; 

    String[] descr = { "Android Course", "HTML 5 Course", "J2SE Course", "JavaScript Course", "MySQL Course", "PHP Course", "CSS Course", "JQuery Course", "C# Course" }; 

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

    lvCourses = (ListView) findViewById(R.id.lvCourses); 

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, Android.R.layout.simple_list_item_1, courses); 

    final TextView rr = (TextView)findViewById(R.id.setT); 
    lvCourses.setAdapter(adapter); 
    lvCourses.setOnItemClickListener(
     new OnItemClickListener() {  

      @Override 
      public void onItemClick(AdapterView<?> lv, View view, int position, long id) { 

       if(position == 0){ 
        rr.setText(""+descr[0]); 
        Intent e = new Intent(getApplicationContext(),TeMainActivity.class); 
        startActivity(e);       
       } 

       if(position == 1){ 
        rr.setText(""+descr[1]); 
        Intent e = new Intent(getApplicationContext(),TeMainActivity.class); 
        startActivity(e); 
       } 
      } 
     }); 
    } 
}

你并不需要检查所有位置的状态。如果你想，当我模拟它给我的错误，以这个数据传递给新的活动

rr.setText(descr[position]); 
Intent e = new Intent(getApplicationContext(),TeMainActivity.class); 
e.putExtra("desc", descr[position]) 
startActivity(e);

只是这样做对onItemClick（）

rr.setText(descr[position]); Intent e = new Intent(getApplicationContext(),TeMainActivity.class); startActivity(e);
