在android代码编译时可能会出现如下错误：
部分代码：
错误提示：OnClickListener cannot be resolved to a type
解决方案：将语句btn_img.setOnClickListener(new OnClickListener(){···}中的OnClickListener改为View.OnClickListener即可
package com.example.activitytest;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Button;
import android.widget.Toast;
public class FirstActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
//隐藏标题栏
requestWindowFeature(Window.FEATURE_NO_TITLE);
//加载布局
setContentView(R.layout.first_layout);
Button button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(FirstActivity.this, "alert aaaaa button1", Toast.LENGTH_SHORT).show();
}
});
}
}
android编译错误“OnClickListener cannot be resolved to a type”
