android过滤第三应用列表

转载自：http://blog.csdn.net/santicom/article/details/7465751

调用所有匹配的第三应用：

publicclassAppFilterActivityextendsActivity
{
@Override
publicvoidonCreate(BundlesavedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

Intentintent=newIntent(Intent.ACTION_ATTACH_DATA);
intent.setType("image/png");

IntentchooserIntent=Intent.createChooser(intent,"Selectapp");
if(chooserIntent==null)
{
return;
}
startActivity(chooserIntent);
}
}

过滤app列表中的某个app:

1,

publicclassAppFilterActivityextendsActivity
{
@Override
publicvoidonCreate(BundlesavedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

Intentintent=newIntent(Intent.ACTION_ATTACH_DATA);
intent.setType("image/png");

showSetAsList(intent);
}

{

List<ResolveInfo>mShareAppLst=mPackageManager.queryIntentActivities(intent,0);
List<ResolveInfo>mAppLst=newArrayList<ResolveInfo>();
intnumActivities=mShareAppLst.size();
//遍历设置为列表，移除设置为列表中的联系人
for(inti=0;i<numActivities;i++)
{
ResolveInforeinfo=mShareAppLst.get(i);
if(reinfo.activityInfo.name.equals("com.android.contacts.activities.AttachPhotoActivity"))
{
continue;
}
mAppLst.add(reinfo);
}
ChooseAppAdaptermAdapter=newChooseAppAdapter(mAppLst,AppFilterActivity.this.getApplicationContext());
AlertDialog.BuilderalertDialog=newAlertDialog.Builder(AppFilterActivity.this);
alertDialog.setTitle("selectapp");
alertDialog.setAdapter(mAdapter,newShareAppItemClickListener(intent,mAppLst,mAdapter)).create().show();
