java - 如何查找 Activity 应用程序名称？

Question

我有这样的代码，当我在剪贴板中复制一些文本时，该程序会自动将文本和应用程序名称粘贴到文本框中。我想粘贴运行/在顶部的应用程序名称

        myClipboard.addPrimaryClipChangedListener(new ClipboardManager.OnPrimaryClipChangedListener() {
        @Override
        public void onPrimaryClipChanged()
        {
            PackageManager pm = getApplicationContext().getPackageManager();
            ApplicationInfo ai;
            try {
                ai = pm.getApplicationInfo(getPackageName(), 0);
            } catch (final PackageManager.NameNotFoundException e) {
                ai = null;
            }
            final String applicationName = (String) (ai != null ? pm.getApplicationLabel(ai) : "(unknown)");
            ClipData cp = myClipboard.getPrimaryClip();
            ClipData.Item item = cp.getItemAt(0);
            String text1 = item.getText().toString();
            pastetext.setText(text1+"---"+applicationName);
        }
    });

获取 Android 上安装的 Activity/应用程序列表:

final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0);

检查所有正在运行的应用程序

ActivityManager actvityManager = (ActivityManager)
this.getSystemService( ACTIVITY_SERVICE );
List<RunningAppProcessInfo> procInfos = actvityManager.getRunningAppProcesses();

如果您想获取您的应用程序或当前在 Android 中打开的应用程序的包名称，请引用此 http://shortcutsandroid.blogspot.in/2015/02/how-to-get-package-name-in-android.html
