[安卓] 1、页面跳转+按钮监听

 

 

技术分享

共2个layout:main.xml和other.xml;2个activity:MainActivity.java,OtherActivity.java


 

在mainactivity中重写onCreate,第6行设置按钮监听~

1 public void onCreate(Bundle savedInstanceState) {2     super.onCreate(savedInstanceState);3     setContentView(R.layout.main);4     Log.v("MainActivity", "onCreate");5     btn = (Button) findViewById(R.id.Main_btn);6     btn.setOnClickListener(this);7     //this.finish(); //结束当前MainActivity8 }

下面是对按钮监听的实现:即当按钮被按下时,跳转到另一页面:

1 @Override2 public void onClick(View arg0) {3     if (arg0 == btn) {4         Intent intent = new Intent();5         intent.setClass(this, OtherActivity.class);6         this.startActivity(intent);7     }8 }

 


另一个activity也类似:

1 public void onCreate(Bundle savedInstanceState) {2     super.onCreate(savedInstanceState);3     setContentView(R.layout.other);4     Log.v("MainActivity", "onCreate");5     btn = (Button) findViewById(R.id.Other_btn);6     btn.setOnClickListener(this);7 }
1 public void onClick(View arg0) {2     if (arg0 == btn) {3         this.finish();4     }5 }

 


有人会觉得OtherActivity为什么是那个样子的,暂时我也不清楚,先把他的xml文件贴下:

 1 <?xml version="1.0" encoding="utf-8"?> 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 3     android:orientation="vertical" 4     android:layout_width="fill_parent" 5     android:layout_height="fill_parent" 6     > 7 <TextView   8     android:layout_width="fill_parent"  9     android:layout_height="wrap_content" 10     android:text="@string/OtherActiviy_hello"11     />12 <Button   13     android:layout_width="fill_parent" 14     android:layout_height="wrap_content" 15     android:text="@string/OtherActiviy_BtnClose"16     android:id="@+id/Other_btn"17     />18 </LinearLayout>
