android - onClickListener 问题

Question

所以我想做一个简单的图像按钮:

<ImageButton
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/button_image" 
    android:contentDescription="@string/desc/>

xml:

public class MainActivity extends ActionBarActivity {
protected void onCreate1 (Bundle savedInstaceState){
    Bundle savedInstanceState;
    super .onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button button1  = (Button) findViewById (R.id.button1);

            View.setOnClickListener(new onClickListener () {
                public void onClick (View v) {
                    Toast.makeText(v.getContext(), "You clicked it. Genius.", Toast.LENGTH_SHORT).show();
                }
            });

但是一直报错:"The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (new onClickListener(){})"

我导入了android.view.View.OnClickLIstener;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.app.ActionBarActivity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;
import android.view.View.OnClickListener;

你应该这样做:

 button1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

            }
        });

使用 button1 并检查 OnClickListener 大小写。
