android之隐式intent调用

直接上代码

MainActivity.java

 1 package com.example.test1; 2  3 import android.app.Activity; 4 import android.content.Intent; 5 import android.net.Uri; 6 import android.os.Bundle; 7 import android.view.View; 8 import android.view.View.OnClickListener; 9 import android.widget.Button;10 11 public class MainActivity extends Activity {12 13     @Override14     protected void onCreate(Bundle savedInstanceState) {15         super.onCreate(savedInstanceState);16         setContentView(R.layout.activity_main);17     18         Button btnButton = (Button) findViewById(R.id.button1);19         20         btnButton.setOnClickListener(new OnClickListener() {21             22             @Override23             public void onClick(View v) {24                 // TODO Auto-generated method stub25                 Intent intent = new Intent();26                 intent.setAction("aa.bb.cc.dd.ee.ff");27                 28                 startActivity(intent);29             }30         });31     }32 }

SecondActivity.java

 1 package com.example.test1; 2  3 import android.app.Activity; 4 import android.content.Intent; 5 import android.os.Bundle; 6 import android.widget.TextView; 7  8 public class SecondActivity extends Activity { 9 10     @Override11     protected void onCreate(Bundle savedInstanceState) {12         13         super.onCreate(savedInstanceState);14         15         setContentView(R.layout.second_main);16 17         Intent intent = getIntent();18         19         TextView textView = (TextView) findViewById(R.id.textView1);20         textView.setText(intent.getAction());21     }22 }

activity_main.xml

 1 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 2     xmlns:tools="http://schemas.android.com/tools" 3     android:layout_width="match_parent" 4     android:layout_height="match_parent" 5     android:paddingBottom="@dimen/activity_vertical_margin" 6     android:paddingLeft="@dimen/activity_horizontal_margin" 7     android:paddingRight="@dimen/activity_horizontal_margin" 8     android:paddingTop="@dimen/activity_vertical_margin" 9     tools:context=".MainActivity" >10 11     <Button12         android:id="@+id/button1"13         android:layout_width="wrap_content"14         android:layout_height="wrap_content"15         android:layout_alignParentTop="true"16         android:layout_centerHorizontal="true"17         android:layout_marginTop="124dp"18         android:text="跳转" />19 20 </RelativeLayout>

second_main.xml

 1 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 2     xmlns:tools="http://schemas.android.com/tools" 3     android:layout_width="match_parent" 4     android:layout_height="match_parent" 5     > 6  7     <TextView 8         android:id="@+id/textView1" 9         android:layout_width="wrap_content"10         android:layout_height="wrap_content"11         android:layout_alignParentLeft="true"12         android:layout_alignParentTop="true"13         android:layout_marginLeft="93dp"14         android:layout_marginTop="176dp"15         android:text="Large Text"16         android:textAppearance="?android:attr/textAppearanceLarge" />17 18 </RelativeLayout>

很重要的AndroidManifest.xml

 1 <?xml version="1.0" encoding="utf-8"?> 2 <manifest xmlns:android="http://schemas.android.com/apk/res/android" 3     package="com.example.test1" 4     android:versionCode="1" 5     android:versionName="1.0" > 6  7     <uses-sdk 8         android:minSdkVersion="8" 9         android:targetSdkVersion="17" />10 11     <application12         android:allowBackup="true"13         android:icon="@drawable/ic_launcher"14         android:label="@string/app_name"15         android:theme="@style/AppTheme" >16         <activity17             android:name="com.example.test1.MainActivity"18             android:label="@string/app_name" >19             <intent-filter>20                 <action android:name="android.intent.action.MAIN" />21 22                 <category android:name="android.intent.category.LAUNCHER" />23             </intent-filter>24         </activity>25         <activity android:name="com.example.test1.SecondActivity">26             <intent-filter>27                 <action android:name="aa.bb.cc.dd.ee.ff"/>28                 29                 <category android:name="android.intent.category.DEFAULT" />//隐式intent调用，这句必须加30             </intent-filter>31         </activity>32 33     </application>34 35 </manifest>
