在我的活动中，我使用SimpleAdapter作为listView。我添加了一个图像和一个textView以显示在listView中。如果我删除图像，那么列表工作正常。意味着我可以点击列表项并且可以转到下一个活动。但是当我添加一个图像时，我无法点击List的项目。这是我下面全码：无法获取onItemClickListener中的项目
Company.java
public class Company extends Activity {
Strings st1 = new Strings();
TextView t1, click;
Button b1, b2, b3;

url=st1.getUrl();
connect1();
}
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
// do something on back.
this.finish();
Intent i = new Intent(Company.this, MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);

请告诉我，我做错了在代码中。
请张贴布局（XML）的文件。 – OAEI 2014-08-30 10:04:29
附加'list_text_black.xml'以及 – 2014-08-30 10:06:01
请检查此行ArrayAdapter adapter = new ArrayAdapter （getApplicationContext（），R.layout.list_text_black，R.id.list_item，r）; arraylist是r并且项目点击r1 –
