浏览器链接打开App

来源：互联网发布：泉州会计网络继续教育编辑：程序博客网时间：2024/05/02 03:05

要使得App可以通过浏览器链接打开，只需要在manifest里对相应Activity配置就可以了，具体配置如下：

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.mingjing.test">    <application        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <activity            android:name=".MainActivity"            android:label="@string/app_name"            android:theme="@style/AppTheme.NoActionBar">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter><!-- ATTENTION: This intent was auto-generated. Follow instructions at  https://g.co/AppIndexing/AndroidStudio to publish your URLs. -->            <intent-filter android:autoVerify="true">                <action android:name="android.intent.action.VIEW" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.BROWSABLE" />                <!-- ATTENTION: This data URL was auto-generated. We recommend that you use the HTTP scheme.                  TODO: Change the host or pathPrefix as necessary. -->                <data                    android:host="test.mingjing.example.com"                    android:pathPrefix="/main"                    android:scheme="mingjing" />            </intent-filter>        </activity>    </application></manifest>

这段代码可以自己敲，不过Android Studio提供了自动生成这段代码的方式：
1.但把光标放在…之间的任意地方，在左边会有一个黄色的小灯泡，点击小灯泡->再点击Add URL,相应的代码就生成成功了，如下图所示:
这里写图片描述
生成的代码如下所示：

<intent-filter>                <action android:name="android.intent.action.VIEW" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.BROWSABLE" />                <!-- ATTENTION: This data URL was auto-generated. We recommend that you use the HTTP scheme.                  TODO: Change the host or pathPrefix as necessary. -->                <data                    android:host="test.mingjing.example.com"                    android:pathPrefix="/main"                    android:scheme="http" />            </intent-filter>

其中host默认时应用的程序名，pathPrefix默认是main,scheme默认时http，这几个值可以根据需要改成任意的字符串，注意pathPrefix要以/开头，只要能和浏览器链接各个部分对上就行了。
下面是测试启动这个页面的Activity代码：

package com.example.mingjing.web;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.webkit.WebResourceRequest;import android.webkit.WebView;import android.webkit.WebViewClient;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);WebView webView = (WebView) findViewById(R.id.wv_test);        webView.loadData("<body><a href=\"mingjing://test.mingjing.example.com/main\">click me!</a></body>","text/html","UTF-8");    }}

其中的链接”mingjing://test.mingjing.example.com/main\”，mingjing对应intent-filter里的scheme,test.mingjing.exmaple.com对应host，main对应pathPrefix,当然也可以在链接后面加上参数如：
mingjing://test.mingjing.example.com/main?id=1002&name=mingjing,这样就可以在被启动的Activity里的NewIntent(Intent intent)方法里拿到传过来的参数，具体如下：

被启动的Activity

activity_layout:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent"    android:gravity="center"    android:background="@android:color/darker_gray">    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:maxWidth="100dp"        android:id="@+id/tv_content"        android:textColor="@android:color/black"        android:gravity="center" /></LinearLayout>

Activity:

package com.example.mingjing.test;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.widget.TextView;/** * Created by mingjing on 16-9-5. */public class MainActivity extends Activity {    /**     * ATTENTION: This was auto-generated to implement the App Indexing API.     * See https://g.co/AppIndexing/AndroidStudio for more information.     */    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        // ATTENTION: This was auto-generated to implement the App Indexing API.        // See https://g.co/AppIndexing/AndroidStudio for more information.        onNewIntent(getIntent());    }    @Override    protected void onNewIntent(Intent intent) {        super.onNewIntent(intent);        Uri data =        intent.getData();        String s = intent.getDataString();        if (intent.getAction().equals(Intent.ACTION_VIEW)) {            String id = data.getQueryParameter("id");            String name = data.getQueryParameter("name");            TextView textView = (TextView) findViewById(R.id.tv_content);            textView.setText("id:" + id + "\nname:" + name);        }    }    @Override    public void onStart() {        super.onStart();        // ATTENTION: This was auto-generated to implement the App Indexing API.        // See https://g.co/AppIndexing/AndroidStudio for more information.    }    @Override    public void onStop() {        super.onStop();    }}

manifest:

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.mingjing.test">    <application        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <activity            android:name=".MainActivity"            android:label="@string/app_name"            android:theme="@style/AppTheme.NoActionBar">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter><!-- ATTENTION: This intent was auto-generated. Follow instructions at  https://g.co/AppIndexing/AndroidStudio to publish your URLs. -->            <intent-filter android:autoVerify="true">                <action android:name="android.intent.action.VIEW" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.BROWSABLE" />                <!-- ATTENTION: This data URL was auto-generated. We recommend that you use the HTTP scheme.                  TODO: Change the host or pathPrefix as necessary. -->                <data                    android:host="test.another"                    android:pathPrefix="/main"                    android:scheme="everystr" />            </intent-filter>        </activity>    </application></manifest>

测试程序的代码：

package com.example.mingjing.web;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.webkit.WebResourceRequest;import android.webkit.WebView;import android.webkit.WebViewClient;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);WebView webView = (WebView) findViewById(R.id.wv_test);        webView.loadData("<body><a href=\"everystr://test.another/main?id=1002&name=mingjing\">click me!</a></body>","text/html","UTF-8");    }}
