嘿伙计们，我在练习时使用的代码遇到了问题。 问题是它对提供教程的人有用，但对我不起作用。我的问题是如何解决它？
package bt.sismo;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;//
import android.widget.ListView;//
import android.widget.ListAdapter;//
import android.widget.ArrayAdapter;//
import android.widget.AdapterView;//
import android.app.Activity;//
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String[] foods = {"Bacon", "Ham", "Tuna", "Candy", "Meatball", "Potato"};
ListAdapter bryansAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, foods);
ListView bryansListView = (ListView) findViewById(R.id.bryansListView);
bryansListView.setAdapter(bryansAdapter);
bryansListView.setOnClickListener(
new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String food = String.valueOf(parent.getItemAtPosition(position));
Toast.makeText(MainActivity.this, food, Toast.LENGTH_LONG).show();
}
}
);
}
}
它后来在 logcat 中给了我这个错误
Error:(26, 23) error: no suitable method found for setOnClickListener(<anonymous OnItemClickListener>)
method View.setOnClickListener(OnClickListener) is not applicable
(argument mismatch; <anonymous OnItemClickListener> cannot be converted to OnClickListener)
method AdapterView.setOnClickListener(OnClickListener) is not applicable
(argument mismatch; <anonymous OnItemClickListener> cannot be converted to OnClickListener)

最佳答案
您正在调用 setOnClickListener 并传入 OnItemClickListener。
更改此:
bryansListView.setOnClickListener(...)
对此:
bryansListView.setOnItemClickListener(...)
关于java - Android 应用程序中的 setOnClickListener 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36917725/
