复制代码 代码如下:


package com.demos;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class GetScreenActivity extends Activity {
private Button firstBtn = null;
private Button secBtn = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
firstBtn = (Button) findViewById(R.id.firstBtn);
secBtn = (Button) findViewById(R.id.secBtn);
firstBtn.setOnClickListener(listener);
secBtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
}
private OnClickListener listener = new OnClickListener(){
@Override
public void onClick(View view) {
}
};
}
