I have the following code:
try {
myVideoView.setMediaController(mediaControls);
File mydir = getDir("myDir", Context.MODE_PRIVATE);
myVideoView.setVideoPath(mydir.getPath()+"/fileName.3gp");
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
myVideoView.requestFocus();
myVideoView.setOnPreparedListener(new OnPreparedListener() {
// Close the progress bar and play the video
public void onPrepared(MediaPlayer mp) {
progressDialog.dismiss();
myVideoView.seekTo(position);
if (position == 0) {
myVideoView.start();
} else {
myVideoView.pause();
}
}
});
within onCreate() method. The problem is that it throws an IOException, and says that Unable to open the content. It works perfect if I use myVideoView.setVideoURI(path/to/server) instead of myVideoView.setVideoPath(path/to/local/storage). All permissions at Manifest.xml are fine, and it does not says that the file was not found or something. It says unable to open it. It is not a video format problem either, because is the same video when I play it from server. If this is a useful info, I have another activity in background (same app), and the VideoView activity is in foreground. Thank you!

Use sharedpreferences to store the result.

SharedPreferences pref = getSharedPreferences("prefs", MODE_PRIVATE);
Editor editor = pref.edit();
if(checkBox.isChecked()){
isChecked=true;
}
editor.putBoolean("checked", isChecked);
editor.apply()
retrieving the data from sharedPreferences.
write the below code just below setContentView();
if(prefs.getBoolean("checked","")==true){
checkBox.setChecked(true);

I have 6 images downloaded as shown here, but the GridView in my gallery only displays 5 of those images.

First time posting, so I apologize if there's anything wrong with this post.
Sorry for being so general and unclear in my post, I wasn't quite sure which portion of the code was the problem area. After looking over the code again, I noticed a stupid mistake. I set GridView's numColumns attribute to 5 in fragment_gallery.xml, but calculated the column width in GalleryFragment.java using private static final int NUM_COLUMNS = 4. I assume that this caused images to be displayed in a non-existent 5th column.
I have implemented Gridview, but the images from the phone gallery is not appearing in the particular GridView.
The scroll seems to be big enough as the scrollbar appearing on the right side scrolls along to the bottom. Then why I couldn't see the images.

I have ViewPager that containing 3 different Fragment. each Fragment containing A Different View and also ListView, I got a problem when I was trying to show the ListView in one of Fragment from ViewPager, it doesn't show anything. I've tried to debug my adapter and it seems my getView() method is not called. I try to call my Fragment not from ViewPager, the result is getView() is called from adapter and ListView is showing. Is there any problem to show ListView from ViewPager? I have tried this solution by calling my adapter from onViewCreated() but there's nothing change. so is there any wrong with my method? this is my code :
My Fragment Class for Managing ViewPager

This is FragmentStatePagerAdapter.java

}
return null;
}
// #Override public float getPageWidth(int position) { return(0.7f); }
#Override
public String getPageTitle(int position) {
return tabsTitles[position];
}
}
this is my Fragment_Provider.xml, Layout for managing my ViewPager

This is of my Fragment in ViewPagerthat containing ListView :
public class Frag_Provider_Terdekat extends Fragment {
private static final String KEY_POSITION="position";
private ListView list_provider;
List<ModelProviderTerdekat> list_ekamedicare;
DB_Esehat db_esehat;
SQLiteDatabase db;
ProviderTerdekatAdapter adapter;
static Frag_Provider_Terdekat newInstance(int position) {
Frag_Provider_Terdekat frag=new Frag_Provider_Terdekat();
Bundle args=new Bundle();
args.putInt(KEY_POSITION, position);
frag.setArguments(args);
return(frag);
}
static String getTitle(Context ctxt, int position) {
return("PROVIDER KU");
}
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState) {
View result=inflater.inflate(R.layout.fragment_child_providerterdekat, container, false);
list_provider = (ListView)result.findViewById(R.id.list_provider);
list_ekamedicare = new ArrayList<ModelProviderTerdekat>();
db_esehat = new DB_Esehat(getActivity());
list_ekamedicare = db_esehat.getProvider();
adapter = new ProviderTerdekatAdapter(getActivity().getApplicationContext(), R.layout.adapter_provider, list_ekamedicare);
list_provider.setAdapter(adapter);
return result;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
#Override
public void onDetach() {
super.onDetach();
}
}
and this is Adapter for my ListView
public class ProviderTerdekatAdapter extends ArrayAdapter<ModelProviderTerdekat> {
List<ModelProviderTerdekat> data = Collections.emptyList();
private LayoutInflater inflater;
private Context context;
static class ViewHolder {
ImageView imvprov_map;
ImageView imvprov_fav;
TextView textprov_nama_rs;
TextView textprov_alamat_rs;
TextView textprov_km_rs;
}
public ProviderTerdekatAdapter (Context context, int viewResourceId, List<ModelProviderTerdekat> data) {
super(context, R.layout.adapter_provider, data);
this.context = context;
inflater = LayoutInflater.from(context);
this.data = data;
}
#Override
public int getCount() {
return data.size();
}
#Override
public long getItemId(int arg0) {
return 0;
}
#Override
public View getView(int position, View view, ViewGroup parent) {
if (view == null) {
view = inflater.inflate(R.layout.adapter_provider, parent, false);
ViewHolder viewHolder = new ViewHolder();
viewHolder.imvprov_map = (ImageView) view.findViewById(R.id.imvprov_map);
viewHolder.imvprov_fav = (ImageView) view.findViewById(R.id.imvprov_fav);
viewHolder.textprov_nama_rs = (TextView) view.findViewById(R.id.textprov_nama_rs);
viewHolder.textprov_alamat_rs = (TextView) view.findViewById(R.id.textprov_alamat_rs);
viewHolder.textprov_km_rs = (TextView) view.findViewById(R.id.textprov_km_rs);
view.setTag(viewHolder);
}
ViewHolder viewHolder = (ViewHolder) view.getTag();
viewHolder.textprov_nama_rs.setText(data.get(position).getRSNAMA());
viewHolder.textprov_alamat_rs.setText(data.get(position).getRSALAMAT());
return view;
}
}
I have no Idea why my GetView() not called in my Adapter, is it because I put in ViewPager? well I hope someone understand about it and help me to solver my problem. thank you very much.
Finally.. I found a solution for my problem, it's because I put ViewPager in RelativeLayout after I change into LinearLayout all view displayed as I wanted
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v4.widget.ContentLoadingProgressBar
android:id="#+id/progressbar"
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:visibility="gone"
android:indeterminate="false" />
<android.support.design.widget.TabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMaxWidth="0dp"
app:tabGravity="fill"
style="#style/MyCustomTabLayout"
app:tabMode="fixed"
android:fillViewport="true"
android:visibility="gone" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1"
android:background="#android:color/white"
android:layout_below="#id/sliding_tabs"
android:visibility="gone"/>
</LinearLayout>
I am trying to get path of photo from gallery which in grid view. this gallery consists of each thumbnail with attached checkbox. Here is the whole code:
public class GridGallery extends Activity
{
ArrayList<String>list;
AlertDialog.Builder alert;
private Button send;
GridView gridView;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.grid_gallery);
DataModel dbModel = new DataModel(this);
list = dbModel.selectAll();
alert = new AlertDialog.Builder(GridGallery.this);
send = (Button)findViewById(R.id.send_message);
gridView = (GridView) findViewById(R.id.sdcard);
gridView.setAdapter(new ImageAdapter(this));
gridView.setClickable(true);
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int pos,
long id)
{
// TODO Auto-generated method stub
final int position = pos;
final String path = list.get(position).toString();
final String option[] = new String[]{"Send to","Watch"};
alert.setTitle("Pick options");
alert.setItems(option, new OnClickListener() {
public void onClick(DialogInterface dialog, int which)
{
// TODO Auto-generated method stub
if(option[which].equals("Watch"))
{
if(path.contains(".jpg"))
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(list.get(position))), "image/jpeg");
startActivity(intent);
}
else if(path.contains(".mp4"))
{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(list.get(position))), "video/*");
startActivity(intent);
}
else
{

intent.setDataAndType(Uri.fromFile(new File(list.get(position))), "audio/*");
startActivity(intent);
}
}//
else
{
Intent sendMail = new Intent(GridGallery.this, SendMessage.class);
sendMail.putExtra("path", path);
startActivity(sendMail);
}
}
}).show();
}
});
send.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
// TODO Auto-generated method stub
String path = null;
Intent sendToMail = new Intent(GridGallery.this, SendMessage.class);

MY problem is I can not be able to click the image or video thumbnail. also how do I able to get the image when I checked the check box.
here is XML code for Image_selection:-

android:layout_height="fill_parent" android:orientation="vertical" android:gravity="center_horizontal">
<ImageView android:id="#+id/item_grid" android:layout_width="100dip" android:layout_height="100dip"/>
<CheckBox android:id="#+id/check" android:layout_width="wrap_content" android:layout_height="wrap_content" />
and grid_gallery.xml:-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical">
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/sdcard"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:numColumns="auto_fit"
android:columnWidth="90dp"
android:stretchMode="columnWidth"
android:gravity="center"
/>
</RelativeLayout>
please help me. Thanks in advance
it seems you store the image path in the ArrayList list. If so, then set an onItemClickListeber for the GridView. in the onItemClick method you get the position of the gridview which was clicked. try 'list.get(position)in theonItemClick` to get the path
