public class Audition1 extends Activity { PRivate ListView listView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_audition1); initComponents(); } private void initComponents() { listView = (ListView) findViewById(R.id.listView); listView.setAdapter(new MyAdapter(this)); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { Toast.makeText(getapplicationContext(), "item", 300).show(); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_audition1, menu); return true; } public final class ViewHolder { public TextView textView; public Button button; public ImageView imageView; } class MyAdapter extends BaseAdapter { private LayoutInflater mInflater; public MyAdapter(Context context) { this.mInflater = LayoutInflater.from(context); } @Override public int getCount() { return 3; } @Override public Object getItem(int position) { return null; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; if (convertView == null) { holder = new ViewHolder(); convertView = mInflater.inflate(R.layout.item, null); holder.imageView = (ImageView) convertView .findViewById(R.id.imageView); holder.textView = (TextView) convertView .findViewById(R.id.textViewId); holder.button = (Button) convertView.findViewById(R.id.button); holder.textView.setText("shit"); holder.button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { AlertDialog.Builder builder = new AlertDialog.Builder( Audition1.this); builder.setMessage("dialog"); builder.setTitle("title"); builder.create(); builder.show(); } }); convertView.setTag(holder); } else { convertView.getTag(); } return convertView; } }

}

LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="match_parent" android:orientation="horizontal"> <TextView android:id="@+id/textViewId" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> <ImageView android:id="@+id/imageView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" android:contentDescription="@string/app_name" /> <Button android:id="@+id/button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="press" android:focusable="false" /> </LinearLayout>

原因是button強制獲取了item的焦點，只要設置button的focusable為false即可。
