Duplicates When Showing Installed Applications in Android
(2 answers)
Closed 7 months ago.
Hello guys can you help me show all installed apps on the main screen? Can you give me some source code of a simple grid view?
Look at this code.
package com.example.android.apis.view;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import java.util.List;
import com.example.android.apis.R;
public class Grid1 extends Activity {
GridView mGrid;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
loadApps(); // do this in onresume?
setContentView(R.layout.grid_1);
mGrid = (GridView) findViewById(R.id.myGrid);
mGrid.setAdapter(new AppsAdapter());
}
private List<ResolveInfo> mApps;
private void loadApps() {
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
mApps = getPackageManager().queryIntentActivities(mainIntent, 0);
}
public class AppsAdapter extends BaseAdapter {
public AppsAdapter() {
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView i;
if (convertView == null) {
i = new ImageView(Grid1.this);
i.setScaleType(ImageView.ScaleType.FIT_CENTER);
i.setLayoutParams(new GridView.LayoutParams(50, 50));
} else {
i = (ImageView) convertView;
}
ResolveInfo info = mApps.get(position);
i.setImageDrawable(info.activityInfo.loadIcon(getPackageManager()));
return i;
}
public final int getCount() {
return mApps.size();
}
public final Object getItem(int position) {
return mApps.get(position);
}
public final long getItemId(int position) {
return position;
}
}
}

I got a source code about GridView.
But, I confused why some code were error.
These are the code. I got error on OnClick Method in MainActivity. Is here anyone help me? Thanks
public void onItemClick(AdapterView <? > AdapterView, View View, int Int, long Long) {
AdapterView = ((ImageItem) imageItems.get(Int)).getTitle();
toDetail(Int, AdapterView);
}
});
I want to each item that when it clicked shown the detailed image and text. I also get code like this but when I clicked "GingerBread" item, it goes to first item ("Astro")
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
ImageItem item = (ImageItem) parent.getItemAtPosition(position);
//Create intent
Intent intent = new Intent(getApplicationContext(), DetailActivity.class);
// intent.putExtra("android.intent.extra.TEXT", Integer.parseInt(getIntent().getStringExtra("android.intent.extra.TEXT")));
intent.putExtra("title", item.getTitle());
//Start details activity
startActivity(intent);
overridePendingTransition(R.anim.home_detail_entry, R.anim.home_detail_exit);
}
});

I am studying android launcher at the moment.
I've succeeded in making the launcher with Gridview with sample code from the web.
However, I don't want to show all the apps installed on the phone, just wanna show selected apps.
Is there any way to do that?
package com.example.gridlauncher;
import java.util.List;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;

import android.widget.GridView;
import android.widget.ImageView;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
public class MainActivity extends Activity {
PackageManager myPackageManager;
public class MyBaseAdapter extends BaseAdapter {
private Context myContext;
private List<ResolveInfo> MyAppList;
MyBaseAdapter(Context c, List<ResolveInfo> l){
myContext = c;
MyAppList = l;
}
#Override
public int getCount() {
return MyAppList.size();
}
#Override
public Object getItem(int position) {
return MyAppList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) {
// if it's not recycled, initialize some attributes
imageView = new ImageView(myContext);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
} else {
imageView = (ImageView)convertView;
}
ResolveInfo resolveInfo = MyAppList.get(position);
imageView.setImageDrawable(resolveInfo.loadIcon(myPackageManager));
return imageView;
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myPackageManager = getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> intentList = getPackageManager().queryIntentActivities(intent, 0);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new MyBaseAdapter(this, intentList));
gridview.setOnItemClickListener(myOnItemClickListener);
}
OnItemClickListener myOnItemClickListener =
new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
ResolveInfo cleckedResolveInfo =
(ResolveInfo)parent.getItemAtPosition(position);
ActivityInfo clickedActivityInfo =
cleckedResolveInfo.activityInfo;
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setClassName(
clickedActivityInfo.applicationInfo.packageName,
clickedActivityInfo.name);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
startActivity(intent);
}
};
}
Between
List<ResolveInfo> intentList = getPackageManager().queryIntentActivities(intent, 0);
and
gridview.setAdapter(new MyBaseAdapter(this, intentList));
just add a white list filter to remove the unneeded items from intentList.
I am trying to develop the master-child page concept using master-detail flow of Android but it comes to the execution , the design is vulnerable to the critics about the poor performance. Would you please tell me some guidelines to increase the performance besudes loading bitmaps with options ?

I have an activity, where in i display list of media files i.e Video, Audio, Images and Animations. On clicking the list item, (as of now Images), the activity must display all the images in the local assets folder in grid View. To do so, i use a single adapter and have a switch case in my getView() function. Depending on the options that is set in the constructor, the switch cases would execute. It works fine for the ListView display, but i am unable to display list of images in grid View. Any help would be apprecaited. Thanks in advance. Here is my code:

each application in the device will be allocated some amount of memory by the DVM. you are getting out of memory error becoz your application is exceeding the memory the allocated by dvm to ur application. for example in froyo, memory allocated for an application is 16Mb. if your application exceeding more than 16Mb, you will get out of memory error. The solution for this is you have to compress the images you are using in your application, and you have to clear all the collection you are using. try clearing all collection you are using once there job is done. you can check how much memory has been consumed by your application in ddms using heap tool. hope this will be helpfull for you.
