我正在开发Android应用程序,它需要listview和ArrayAdapter。现在我想在此 ListView 上 onItemClickListener 。但是 IDE Anacode(与 Eclipse 相同)显示错误!
我已经尝试过此类问题帖子中的所有答案。但没有帮助!
请帮忙
//the code
package edward.harsh.friends;
import android.app.*;
import android.os.*;
import android.view.*;
import android.widget.*;
public class ListViewSampleActivity extends Activity
{
ListView mCountriesLV;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/**
* Get the control instances from the main.xml layout
*/
mCountriesLV = (ListView) findViewById(R.id.countriesLV);
mCountriesLV.setAdapter(new CountriesAdapter(this, R.layout.listview_country_row, mCountriesList));
mCountriesLV.setOnItemClickListener(
new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getApplicationContext()," name", Toast.LENGTH_SHORT).show();
}
});
}
}
错误消息是
The method setOnItemClickListener(AdapterView.OnItemClickListener in the type
AdapterView <ListAdapter> is not applicable for the arguments (new OnItemClickListener(){})
OnItemClickListener cannot be resolved to a type
正如一些人的建议。我什至尝试过这个
mCountriesLV.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getApplicationContext()," name", Toast.LENGTH_SHORT).show();
}
});
但它抛出另一个错误
The type new AdapterView.OnItemClickListener(){} must implement the inherited abstract method
AdapterView.OnItemClickListener.onItemClick(AdapterView <?>, View, int, long)
最佳答案
尝试在setOnItemClickListener方法中添加AdapterView.OnItemClickListener(),它不适用于OnItemClickListener
mCountriesLV.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
关于java - ListView 与 ArrayAdapter 中的 setOnItemClickListener 错误,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/40542291/
