Android的当前应用启动第三方应用（跨软件启动页面）

当我们需要在一个软件页面里调用另一个软件的某个页面，这时就需要跨软件启动页面，比如我们在自己的页面里调用支付宝或微信的页面。

1.方法1

第一步：在A软件的页面配置文件里添加android:exported=”true”

第二步：在A软件的页面配置文件里添加intent-filter标签，格式为：

<intent-filter >
<action android:name="命名"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>

例：

第三步：在B软件里启动A软件里的页面，如

Intent i=new Intent("zhao.sizhe.a");
startActivity(i);

常用包名
// 微信包名 com.tencent.mm //启动类名：com.tencent.mm.ui.LauncherUI

//QQ 包名 com.tencent.mobileqq //启动类名：com.tencent.mobileqq.activity.HomeActivity

//支付宝包名：com.eg.android.AlipayGphone //启动类名com.eg.android.AlipayGphone.FastStartActivity

//钉钉包名：com.alibaba.android.rimet //启动类名：com.alibaba.android.rimet.biz.home.activity.HomeActivity

//QQ空间包名：com.qzone

//QQ手机管家包名：com.tencent.qqpimsecure

//微博包名：com.sina.weibo //启动类名：com.sina.weibo.EditActivity

2.方法2

通过app的包名和类名

 Intent intent = new Intent();              ComponentName comp = new ComponentName("com.tencent.mobileqq", "com.tencent.mobileqq.activity.SplashActivity");//QQ的包名和类名// ComponentName comp = new ComponentName("com.tencent.mm", "com.tencent.mm.ui.LauncherUI");//微信的包名和类名
// ComponentName comp = new ComponentName("com.eg.android.AlipayGphone", "com.eg.android.AlipayGphone.FastStartActivity");//支付宝intent.setComponent(comp);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
//finish();

3.方法3

通过包名

private void doStartApplicationWithPackageName(String packagename) {// 通过包名获取此APP详细信息，包括Activities、services、versioncode、name等等PackageInfo packageinfo = null;try {packageinfo = getPackageManager().getPackageInfo(packagename, 0);} catch (PackageManager.NameNotFoundException e) {e.printStackTrace();}if (packageinfo == null) {return;}// 创建一个类别为CATEGORY_LAUNCHER的该包名的IntentIntent resolveIntent = new Intent(Intent.ACTION_MAIN, null);resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);resolveIntent.setPackage(packageinfo.packageName);// 通过getPackageManager()的queryIntentActivities方法遍历List<ResolveInfo> resolveinfoList = getPackageManager().queryIntentActivities(resolveIntent, 0);ResolveInfo resolveinfo = resolveinfoList.iterator().next();if (resolveinfo != null) {// packagename = 参数packnameString packageName = resolveinfo.activityInfo.packageName;// 这个就是我们要找的该APP的LAUNCHER的Activity[组织形式：packagename.mainActivityname]String className = resolveinfo.activityInfo.name;// LAUNCHER IntentIntent intent = new Intent(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_LAUNCHER);// 设置ComponentName参数1:packagename参数2:MainActivity路径ComponentName cn = new ComponentName(packageName, className);intent.setComponent(cn);startActivity(intent);}}

方法3.案例：

在Java文件添加以下代码：

package com.example.tiaozhuangapp;import androidx.appcompat.app.AppCompatActivity;

//                Intent i=new Intent("a.b.c");//               startActivity(i);//                Intent intent = new Intent();
//                ComponentName comp = new ComponentName("com.tencent.mobileqq", "com.tencent.mobileqq.activity.SplashActivity");//     ComponentName comp = new ComponentName("com.tencent.mm", "com.tencent.mm.ui.LauncherUI");

//                startActivity(intent);
//                finish();doStartApplicationWithPackageName("com.tencent.mobileqq");}});bt2.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.tencent.mm");}});bt3.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.eg.android.AlipayGphone");}});bt4.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.taobao.taobao");}});bt5.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.tencent.qqmusic");}});bt6.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.tencent.mtt");}});bt7.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.ss.android.ugc.aweme");}});bt8.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {//   Intent i=new Intent(MainActivity.this,MainActivity2.class);//  startActivity(i);//  finish();}});bt13.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.tencent.qqlive");}});bt14.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.baidu.tieba");}});bt15.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.chaoxing.mobile");}});bt16.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("net.csdn.csdnplus");}});bt17.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.tencent.wework");}});bt18.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.kingsoft");}});bt19.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {doStartApplicationWithPackageName("com.kingsoft");}});}private void doStartApplicationWithPackageName(String packagename) {// 通过包名获取此APP详细信息，包括Activities、services、versioncode、name等等PackageInfo packageinfo = null;try {packageinfo = getPackageManager().getPackageInfo(packagename, 0);} catch (PackageManager.NameNotFoundException e) {e.printStackTrace();}if (packageinfo == null) {return;}// 创建一个类别为CATEGORY_LAUNCHER的该包名的IntentIntent resolveIntent = new Intent(Intent.ACTION_MAIN, null);resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);resolveIntent.setPackage(packageinfo.packageName);// 通过getPackageManager()的queryIntentActivities方法遍历List<ResolveInfo> resolveinfoList = getPackageManager().queryIntentActivities(resolveIntent, 0);ResolveInfo resolveinfo = resolveinfoList.iterator().next();if (resolveinfo != null) {// packagename = 参数packnameString packageName = resolveinfo.activityInfo.packageName;// 这个就是我们要找的该APP的LAUNCHER的Activity[组织形式：packagename.mainActivityname]String className = resolveinfo.activityInfo.name;// LAUNCHER IntentIntent intent = new Intent(Intent.ACTION_MAIN);intent.addCategory(Intent.CATEGORY_LAUNCHER);// 设置ComponentName参数1:packagename参数2:MainActivity路径ComponentName cn = new ComponentName(packageName, className);intent.setComponent(cn);startActivity(intent);}}}
