如何在内部类中引用父类的成员
本人新手 刚刚开始学 请多多指教
按照教材写代码碰到诸多问题.. 说起来都是泪....
首先贴代码
package com.xynet.test1;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.*;
import android.content.*;
public class MainActivity extends Activity {
private Button login_btn=null;
private EditText number1; //这里定义成员变量
private EditText number2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText number1=(EditText) findViewById(R.id.number_1);
EditText number2=(EditText) findViewById(R.id.number_2);
Button login_btn = (Button)findViewById(R.id.login_btn);
login_btn.setText(R.string.login_btn_wait);
//login_btn.setOnClickListener(new login_btnlistenger());
login_btn.setOnClickListener(new login_btnlistenger());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
class login_btnlistenger implements OnClickListener{
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
MainActivity.this.number1.setText("3"); //在这里引用失败 一执行到这里便 //强制退出, 这句是调试用的 实际要在下面两句 获取这两个控件的值, 都是按教材上写的..
//String numberone = number1.getText().toString();
//String numbertwo = number2.getText().toString();
Intent intent = new Intent();
//intent.putExtra("tips_one", number_one);
//intent.putExtra("tips_two", number_two);
intent.setClass(MainActivity.this,OtherActivity.class);
MainActivity.this.startActivity(intent);
}
}
}
