获取最近安装的包的图标

Question

我收到了最近通过实施 broadcastreceiver 的 onReceive() 添加的包的名称和其他详细信息，但我不知道如何获取该包的图标。我无法在 brodcast Receiver

中获得 packageManager()

是否可以从 intent 获取图标？？

public class PackageActionsReceiver extends BroadcastReceiver {

private static final String TAG = PackageActionsReceiver.class
        .getSimpleName();

@Override
public void onReceive(Context context, Intent intent) {
    if (UtilSharedPreference.isRegistered(context)) {
        Log.d(TAG, "onReceiver");
        Uri data = intent.getData();
        Package packageBean = new Package();
        Drawable tempDrawableImage;
        packageBean.setPackageName(data.getEncodedSchemeSpecificPart());
        if (intent.getAction().equals(
                Intent.ACTION_PACKAGE_ADDED.toString())) {
            packageBean.setInfo("I");
        } else if (intent.getAction().equals(Intent.ACTION_PACKAGE_REMOVED)) {
            packageBean.setInfo("U");
        } else if (intent.getAction()
                .equals(Intent.ACTION_PACKAGE_REPLACED)) {
            packageBean.setInfo("R");
        }
        packageBean.setName(Utils.getApplicationName(context, intent
                .getData().getEncodedSchemeSpecificPart(),
                PackageManager.GET_UNINSTALLED_PACKAGES));
        packageBean.setDate(System.currentTimeMillis());

        PackageDataSource packageSource = new PackageDataSource(context);
        packageSource.open();
        packageSource.addNewPackage(packageBean);
        packageSource.close();
    }
}

}

Answer 1

您可以从 onReceive 方法的上下文中获取 packageManager

例如

public void onReceive(Context context, Intent intent) {
context.getPackageManager()
}

你可以使用这个答案

Drawable icon = context.getPackageManager().getApplicationIcon("com.example.testnotification");
imageView.setImageDrawable(icon);
