举例如下：
public class UI extends JFrame{
private JButton button
public UI(){
button=new JButton()
button.setToolTipText("这是什么按钮？")
this.add(button)
this.setSize(200,300)
this.setDefaultCloseOperation(this.EXIT_ON_CLOSE)
this.setVisible(true)
}
public static void main(String[] args){
new UI()
}
}
@Overridepublic void onClick(View v) {
final EditText et = new EditText(context)
new AlertDialog.Builder(context)
.setTitle("说明")
.setMessage("单个页卡内按钮事件测试")
.setView(et)
.setPositiveButton("确定",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(context, "单击确定按钮", Toast.LENGTH_LONG).show()
}
}).setNegativeButton("取消",null).show()
}
