im设置了一个带有listView对象的主要活动，但是，ListView不会响应触摸，OnItemClick和OnContextItemselected无法到达，我设置查看我的错误，这是我的代码：
public class MainActivity extends Activity implements OnClickListener, OnItemClickListener {
long selectedMovieId;
DbHandler dbhandler;
Movie selectedMovie;
MovieAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn_setting = (Button) findViewById(R.id.page_main_setting);
Button btn_add = (Button) findViewById(R.id.page_main_add);
ListView lv = (ListView) findViewById(R.id.list);
btn_add.setOnClickListener(this);
btn_setting.setOnClickListener(this);
lv.setOnItemClickListener(this);
dbhandler = new DbHandler(this);
registerForContextMenu(lv);
Cursor c = dbhandler.queryAll();
startManagingCursor(c);
adapter = new MovieAdapter(this, c);
lv.setAdapter(adapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_options, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.main_options_exit:
finish();
return true;
case R.id.main_option_delete_all:
dbhandler.deleteAll();
refresh();
return true;
}
return false;
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub
getMenuInflater().inflate(R.menu.main_context, menu);
}
@Override
public boolean onContextItemSelected(MenuItem item) {
Log.d("context menu", "clicked");
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
selectedMovieId = info.id;
switch (item.getItemId()) {
case R.id.main_context_edit:
Intent intent = new Intent(this, AddEditActivity.class);
intent.putExtra(DbConstants.FROM_CONTEXT, selectedMovie+"");
startActivity(intent);
return true;
case R.id.main_context_delete:
dbhandler.deleteMovie(selectedMovieId);
refresh();
return true;
}
return false;
}
@Override

switch (v.getId()) {

openOptionsMenu();
break;

它必须与列表的布局有关，插入它旁边的一个简单列表
OnItemClick事件现在由RatingBar拦截。
将OnTouchEvent侦听器添加到您的评分栏中，然后返回false，以说ConatingBar无法处理此事件。
@Override
public boolean onTouchEvent(MotionEvent event) {
super.onTouchEvent(MotionEvent event)
return false;
}
编辑：上面的答案用于子分类RatingBar。
但是您已经有onTouchEvent仅return false而不是True。
问题在于，适配器的布局中有一个滚动视图对象，将其删除，问题将被修复
