在Android中設(shè)置一個(gè)按鈕，點(diǎn)擊按鈕跳轉(zhuǎn)至另一個(gè)頁(yè)面。編寫完成后，運(yùn)行不了，點(diǎn)擊該按鈕，程序自動(dòng)關(guān)閉。求求各位大神幫我看看哪里有問(wèn)題。1.這是main.java.里的相關(guān)代碼 @Override             public void onClick(View arg0) {                 Intent intent=new Intent(MainActivity.this,TwoActivity.class);                 startActivity(intent);             }2.這是two.Java里的代碼 package com.jikexueyuan.testqrcode; import android.app.Activity; import android.os.Bundle; public class TwoActivity extends Activity {  @Override protected void onCreate(Bundle saveInstanceState){      super.onCreate(saveInstanceState);      setContentView(R.layout.two);  } }3.這是main.xml的代碼 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:id="@+id/container"     android:orientation="vertical"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context="com.jikexueyuan.testqrcode.MainActivity"     tools:ignore="MergeRootFrame" > <Button         android:id="@+id/gen"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_marginTop="36dp"        android:text="生成二維碼"        />     </LinearLayout>4.這是two.xml里的代碼 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical" >     <Button         android:id="@+id/button1"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="名片" />     <Button         android:id="@+id/button2"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="短信" /></LinearLayout>
