隐藏应用程序图标

Question

我正在做一个Android应用程序.我想在模拟器中隐藏应用程序图标,我想通过按一些数字来启动我的应用程序,例如456#.有没有办法做到这一点？

Answer 1

要以编程方式从启动器隐藏应用程序图标,您可以执行此操作

    PackageManager packageManager = context.getPackageManager();
    ComponentName componentName = new ComponentName(context,
            LauncherActivity.class);
    packageManager.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
            PackageManager.DONT_KILL_APP);

要通过按数字启动应用程序,请首先在mainfest文件中添加以下权限

     <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>

然后注册接收器

<receiver android:name=".LaunchAppViaDialReceiver"> 
    <intent-filter> 
    <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
    </intent-filter> 
</receiver>

然后创建一个接收器类

  public class LaunchAppViaDialReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Bundle bundle = intent.getExtras();
    if (null == bundle)
        return;
    String phoneNubmer = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
             //here change the number to your desired number
    if (phoneNubmer.equals("12345")) {
        setResultData(null);
        Gaurdian.changeStealthMode(context,
                PackageManager.COMPONENT_ENABLED_STATE_ENABLED);
        Intent appIntent = new Intent(context, LauncherActivity.class);
        appIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(appIntent);
    }

}

如果你想隐藏应用程序图标,最好首先显示图标,让用户知道图标消失后如何启动应用程序.首先在清单中创建一个活动别名,然后在那里移动您的intent过滤器.这样,您可以在不禁用活动的情况下禁用图标.

<activity
    android:name=".MainActivity"
    android:label="@string/app_name" >
</activity>
<activity-alias
    android:name=".Launcher" 
    android:targetActivity=".MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter> 
</activity-alias>

使用您的包名称获取启动器别名的组件名称:

private static final ComponentName LAUNCHER_COMPONENT_NAME = new ComponentName(
            "your.package.name", "your.package.name.Launcher");

你可以检查它是否已被禁用...

private boolean isLauncherIconVisible() {
    int enabledSetting = getPackageManager()
            .getComponentEnabledSetting(LAUNCHER_COMPONENT_NAME);
    return enabledSetting != PackageManager.COMPONENT_ENABLED_STATE_DISABLED;
}

...并在提供用户信息后在适当时禁用它:

private void hideLauncherIcon() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Important!");
    builder.setMessage("To launch the app again, dial phone number 12345.");
    builder.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            getPackageManager().setComponentEnabledSetting(LAUNCHER_COMPONENT_NAME,
                    PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
                    PackageManager.DONT_KILL_APP);
        }
    });
    builder.setIcon(android.R.drawable.ic_dialog_alert);
    builder.show();
}

要从拨号器启动,请创建一个广播接收器:

public class LaunchViaDialReceiver extends BroadcastReceiver {

    private static final String LAUNCHER_NUMBER = "12345";

    @Override
    public void onReceive(Context context, Intent intent) {
        String phoneNubmer = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        if (LAUNCHER_NUMBER.equals(phoneNubmer)) {
            setResultData(null);
            Intent appIntent = new Intent(context, MainActivity.class);
            appIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(appIntent);
        }
    }
}

将其添加到清单:

<receiver android:name=".LaunchViaDialReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
    </intent-filter>
</receiver>

并向清单添加权限:

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />

回答问题的第一部分,试试这段代码:

PackageManager pm = getApplicationContext().getPackageManager(); 
pm.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

您的应用程序将不可见,但用户仍可在设置>>应用程序>>管理应用程序中找到它

这个答案也可能对你有所帮助.
