java - 取消定义 packageName 并捕获图标

Question

我正在尝试获取数据库导向应用程序的 Package Name 并缩进应用程序的包图标并将其设置在 ImageView 中

到目前为止，我能够构建的是:

try {
    Cliente movieDetailsVO=myDb.getFav(0); // DB sqlite

    // Erro here next line --V
    Drawable icon=getPackageManager().getApplicationIcon(movieDetailsVO.getCOLPM()); // <== get ID package app banco de dados
    imgIcon.setImageDrawable(icon);
} catch (PackageManager.NameNotFoundException e) {
    e.printStackTrace();
}

有人可以帮助我...

我是这样的

Cliente movieDetailsVO = myDb.getFav(0);
txtMovieNameDisplay.setText(movieDetailsVO.getNAME());
String packageName = movieDetailsVO.getCOLPM(); 

try {

    Drawable icon = getContext().getPackageManager().getApplicationIcon(packageName);
    imgIcon.setImageDrawable(icon);
} catch (PackageManager.NameNotFoundException ne) {

}

您可以获得应用程序图标及其启动Intent，如下所示:

Cliente movieDetailsVO = myDb.getFav(0);
String packageName = movieDetailsVO.getCOLPM(); // Be sure about package name correctness

Drawable drawable = null;
try {
    drawable = getPackageManager().getApplicationIcon(packageName);
} catch (Exception ignored) {
}
Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);

// Try to use glide to show images into an ImageView
Glide.with(getApplicationContext()).load(drawable).into(imgIcon);
