How to launch gallery如何启动自带的Gallery

被Android的Gallery搞疯了，没有一个统一的Intent可以打开而不是选择，没办法，遍历全部的Activity，找到可能是Gallery的Activity，代码如下：

package com.test; import android.os.Bundle; import android.app.Activity; import android.content.Intent; import android.content.pm.ResolveInfo; public class Main extends Activity { @Override public void onCreate( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( R.layout.main ); Intent intent = new Intent( Intent.ACTION_MAIN, null ); intent.addCategory( Intent.CATEGORY_LAUNCHER ); java.util.List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 ); findActivity( list, "gallery" ); //We hope each gallery activity has "gallery" in its package name } private final void findActivity( java.util.List<ResolveInfo> list, String key ) { if( list == null || key == null ){ return; } String findKey = key.toLowerCase(); Object object = null; ResolveInfo info = null; for( int i = 0, count = list.size(); i < count; i ++ ) { object = list.get( i ); if( object instanceof ResolveInfo ) { info = (ResolveInfo)object; if( info.activityInfo.name == null ){ continue; } if( info.activityInfo.name.toLowerCase().indexOf( findKey ) > -1 ) { System.err.println( info.activityInfo.packageName + " " + info.activityInfo.name ); tryLaunch( info.activityInfo.packageName, info.activityInfo.name ); } } } } private final void tryLaunch( String packageName, String name ) { if( packageName == null || name == null ){ return; } Intent intent = new Intent( Intent.ACTION_VIEW, null ); intent.setClassName( packageName, name ); try{ startActivityForResult( intent, 0 ); }catch( Exception e ){ e.printStackTrace(); } } }

 

测试Motorola和模拟器是可以的，HTC不行，莫非HTC的没有使用Gallery的名称？没有HTC的真机，头疼！

 

private final void sendViewGalleryIntent() { List<ResolveInfo> list = getActivities(); try{ findAndLaunchActivity( list, "gallery" ); return; }catch( Exception e ){ e.printStackTrace(); } try{ findAndLaunchActivity( list, "album" ); return; }catch( Exception e ){ e.printStackTrace(); showErrorToast( e ); } //launchActivity( "com.android.camera", "com.android.camera.GalleryPicker", null ); } private final List<ResolveInfo> getActivities() { Intent intent = new Intent( Intent.ACTION_MAIN, null ); intent.addCategory( Intent.CATEGORY_LAUNCHER ); return getPackageManager().queryIntentActivities( intent, 0 ); } private final void findAndLaunchActivity( List<ResolveInfo> list, String key ) { if( list == null || key == null ){ return; } String findKey = key.toLowerCase(); Object object = null; ResolveInfo info = null; for( int i = 0, count = list.size(); i < count; i ++ ) { object = list.get( i ); if( object instanceof ResolveInfo ) { info = (ResolveInfo)object; if( info.activityInfo.name == null ){ continue; } if( info.activityInfo.name.toLowerCase().indexOf( findKey ) > -1 ) { launchActivity( info.activityInfo.packageName, info.activityInfo.name, null ); return; } } } } private final void launchActivity( String packageName, String name, Uri uri ) { Intent intent = new Intent( Intent.ACTION_VIEW, uri ); intent.setClassName( packageName, name ); startActivityForResult( intent, 0 ); }
