Question

我正在开发一个应用程序，我用包管理器列出已安装的应用程序。我可以获取项目的包名称，但我想根据包启动详细信息屏幕。因此，例如，如果在列表中选择了Dolphin Browser，您将看到以下图像。我怎么能这样做？

enter image description here

最终解决方案将您的目标设置为Gingerbread API级别9，并将您的min设置为API级别7

final int apiLevel = Build.VERSION.SDK_INT;
Intent intent = new Intent();
if (apiLevel >= 9) {
    //TODO get working on gb
    //Toast.makeText(SDMove.this, "Gingerbread Not Currently Supported", Toast.LENGTH_LONG).show();
    startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS,
                             Uri.parse("package:" + pli.pkg.packageName)));
} else {
    final String appPkgName = (apiLevel == 8 ? "pkg" : "com.android.settings.ApplicationPkgName");
    intent.setAction(Intent.ACTION_VIEW);
    intent.setClassName("com.android.settings", "com.android.settings.InstalledAppDetails");
    intent.putExtra(appPkgName, pli.pkg.packageName);
    startActivity(intent);
}

Answer 1

试试这个：

startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:your.package.here")));

将“package：your.package.here”替换为您要查看的真实包...

这是一款功能齐全的应用，其ListActivity列出了所有已安装的应用。单击包名称时，将打开应用程序详细信息。

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // Intent for getting installed apps.
    Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
    mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);

    // Get installed apps
    List<ResolveInfo> appList = this.getPackageManager().queryIntentActivities(mainIntent, 0);

    // Make new list for package names and fill the list.
    List<String> packageNameList = new ArrayList<String>();
    for (ResolveInfo resolveInfo : appList) {
        packageNameList.add(resolveInfo.activityInfo.packageName);
    }

    // Set the list adapter.
    setListAdapter(new ArrayAdapter<String>(this, R.layout.simple, packageNameList));
}

public void onListItemClick(ListView l, View v, int position, long id)
{
    // Get the TextView that was clicked.
    TextView view = (TextView)v;

    // Get the text from the TextView.
    String packageName = (String)view.getText();

    // Open AppDetails for the selected package.
    showInstalledAppDetails(packageName);
}

public void showInstalledAppDetails(String packageName) {
    final int apiLevel = Build.VERSION.SDK_INT;
    Intent intent = new Intent();

    if (apiLevel >= 9) {
        intent.setAction(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        intent.setData(Uri.parse("package:" + packageName));
    } else {
        final String appPkgName = (apiLevel == 8 ? "pkg" : "com.android.settings.ApplicationPkgName");

        intent.setAction(Intent.ACTION_VIEW);
        intent.setClassName("com.android.settings", "com.android.settings.InstalledAppDetails");
        intent.putExtra(appPkgName, packageName);
    }

    // Start Activity
    startActivity(intent);
}

请记得 main.xml ：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <ListView  
        android:id="@android:id/list"
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content"/>
    <TextView android:id="@android:id/empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="No apps installed"/>
</LinearLayout>

和 simple.xml ：

<?xml version="1.0" encoding="utf-8"?>
<TextView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
</TextView>

启动应用的应用信息设置。

Uri uri = new Uri.Builder()
        .scheme("package")
        .opaquePart(getPackageName())
        .build();
startActivity(new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS, uri));

Answer 4

这是这样做的方法，这是使用来自您的应用程序的构建信息的通用答案。您必须使用 FLAG_ACTIVITY_NEW_TASK 并为您的应用构建正确的 URI。

  // Build intent that displays the App settings screen.
    Intent intent = new Intent();
                                intent.setAction(
    Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
    Uri uri = Uri.fromParts("package",
            BuildConfig.APPLICATION_ID, null);
                                intent.setData(uri);
                                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);

例如，您可以在小吃店使用它。

Snackbar.make(
    findViewById(R.id.activity_layout),
    "snackbar text",
    Snackbar.LENGTH_INDEFINITE)
            .setAction("Settings", new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // Build intent that displays the App settings screen.
            Intent intent = new Intent();
            intent.setAction(
                    Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
            Uri uri = Uri.fromParts("package",
                    BuildConfig.APPLICATION_ID, null);
            intent.setData(uri);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intent);
        }
    })
            .show();
