if(view==null)
{
//INFLATE CUSTOM LAYOUT
view= LayoutInflater.from(c).inflate(R.layout.model,viewGroup,false);
}
final PDFDoc pdfDoc= (PDFDoc) this.getItem(i);
TextView nameTxt= (TextView) view.findViewById(R.id.nameTxt);

Include this permission in manifest if you are storing pdf in external storage.
Use Asset folder like this
AssetManager assetManager = getAssets();
File file = new File(getFilesDir(), "xyz.pdf");
in = assetManager.open("xyz.pdf");
out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE);
copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
out = null;

You can open it as an input stream like this from a fragment
reader = new BufferedReader(new InputStreamReader(getActivity().getAssets().open(myfile.pdf))
You don't need permisssions as you're accessing your app's internal files but putting pdf into assets can increase the weight of the app , be careful
and then you can save it as string like that
private StringBuilder text = new StringBuilder();
String mLine;
while ((mLine = reader.readLine()) != null) {
text.append(mLine);
text.append('\n');
}
if (reader != null) {
try {
reader.close();
} catch (IOException e) {
//log the exception
}

The PDF renderer class is not rendering a PDF on Android SDK 21

Here's the code I'm using to render a PDF called "answerkey.pdf" that's stored in "Download/Adobe Reader/answerkey.pdf"

public class MainActivity extends Activity {
private ImageView imageView;
private Button next, previous;
private TextView tv;
private int currentPage = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
next = (Button)findViewById(R.id.next);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
currentPage++;
render();
}
});
previous = (Button)findViewById(R.id.previous);
previous.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
currentPage--;
render();
}
});
// tv = (TextView)findViewById(R.id.testText);
// tv.setText(Environment.getExternalStorageDirectory().getAbsolutePath());
//
// Toast toast = Toast.makeText(getApplicationContext(),Environment.getExternalStorageDirectory().getAbsolutePath(),Toast.LENGTH_LONG);
// toast.show();
}
private void render() {
try {
imageView = (ImageView)findViewById(R.id.imageView);
int REQ_WIDTH = 1;
int REQ_HEIGHT = 1;
REQ_WIDTH = imageView.getWidth();
REQ_HEIGHT = imageView.getHeight();
Bitmap bitmap = Bitmap.createBitmap(REQ_WIDTH, REQ_HEIGHT, Bitmap.Config.ARGB_4444);
File file = new File(Environment.getDataDirectory().getPath()+"Adobe Reader/answerkey.pdf");
PdfRenderer pdfRenderer = new PdfRenderer(ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY));
if(currentPage < 0) {
currentPage=0;
}
else if (currentPage > pdfRenderer.getPageCount()) {
currentPage = pdfRenderer.getPageCount()-1;
}
Matrix matrix = imageView.getImageMatrix();
Rect rect = new Rect(0,0,REQ_HEIGHT,REQ_WIDTH);
pdfRenderer.openPage(currentPage).render(bitmap,rect,matrix,PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);
imageView.setImageMatrix(matrix);
imageView.setImageBitmap(bitmap);
imageView.invalidate();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Here's the layout.xml file I've made -
<?xml version="1.0" encoding="utf-8"?>

For some reason, the PDF just isn't being displayed on screen, I keep getting a white, blank background. What am I doing wrong? Is the path incorrect? I have no SD card on my device. Or am I doing something wrong with the bitmap?

Is the path incorrect?
Yes.
I have no SD card on my device
That is fine. That would be removable storage. I am interpreting "Download/Adobe Reader/answerkey.pdf" as referring to something on external storage.
The recommended way to get this location would be to replace:
File file = new File(Environment.getDataDirectory().getPath()+"Adobe Reader/answerkey.pdf");
with:
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "Adobe Reader/answerkey.pdf");
Note that your app will need to request the READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE permission, and that will involve runtime permissions on Android 6.0+ (if your targetSdkVersion is 23 or higher).

VideoView Loader Android

I have implemented videoview in one of my fragment. It's working fine but there is one problem I am unable to set a loader or progress bar over the videoview. My progressbar is working for the whole screen but I only want it over the videoview so that user can understand that a video is loading.
Below is my java and xml code.Please help me with the solution.

mediacontroller.setAnchorView(videoview);
Uri video = Uri.parse(VideoURL);
videoview.setMediaController(mediacontroller);
videoview.setVideoURI(video);
videoview.start();
progressBar.setVisibility(View.VISIBLE);

Below is main activity xml on which i am inflating my fragment two.

android:layout_marginLeft="20dp"
android:layout_marginRight="32dp"
android:layout_height="130dp"/>
</RelativeLayout>
</android.support.constraint.ConstraintLayout>

Please use the following xml to replace your fragment_two.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:id="#+id/video"
android:layout_width="match_parent"

/>
<ProgressBar
android:id="#+id/progressBar1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
/>
</FrameLayout>

Try using RelativeLayout in fragment_two.xml instead of LinearLayout and put your progressbar on top of videoview.

Rest Template PUT method In Android

I'm new to Android and Rest Template.I have developed a android
screen and display JSON data using Rest Template GET method on my
screen.My next step is to update some fields like edit name and add
missing things and save back to the rest Template.
public class MyPreferences extends AppCompatActivity {
TextView tv;
private Listcp = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_preferences);
Resources resources = getResources();
Log.d("Consumer pojo", "onCreate:");
new HttpRequestTask().execute();
}
private class HttpRequestTask extends AsyncTask<Void, Void, ConsumerProfile>{
#Override
protected ConsumerProfile doInBackground(Void... params) {
try {
final String url = "http://192.168.1.213:9001/consumer/local/"+LoginFragment.CONSUMEROBJECT.getId();
RestTemplate restTemplate = new RestTemplate();
ConsumerProfile cp = restTemplate.getForObject(url, ConsumerProfile.class);
return cp;
}catch (Exception e){
Log.e("MainActivity", e.getMessage(),e );
}
return null;
}
#Override
protected void onPostExecute(ConsumerProfile cp){
super.onPostExecute(cp);
Log.d("cppppppppppppppppppppp", "onPostExecute: " + cp.getId());
TextView fname=(TextView)findViewById(R.id.editfname);
TextView mname=(TextView)findViewById(R.id.editmname);
TextView lname=(TextView)findViewById(R.id.editlname);
TextView nname=(TextView)findViewById(R.id.editnname);
TextView dob=(TextView)findViewById(R.id.editdob);
TextView status=(TextView)findViewById(R.id.editstatus);
TextView homeAddress=(TextView)findViewById(R.id.edithomeAddr);
TextView workAddress=(TextView)findViewById(R.id.editworkAddr);
TextView income=(TextView)findViewById(R.id.editincome);
fname.setText(cp.getFirstName());
mname.setText(cp.getMiddleName());
lname.setText(cp.getLastName());
nname.setText(cp.getNickName());
dob.setText(cp.getDob());
status.setText(cp.getStatus());
homeAddress.setText(cp.getHomeAddress());
workAddress.setText(cp.getWorkAddress());
income.setText(cp.getIncome());
}
}This Screen is for Get Method
This is what I did Up to Now.
This code is for Get method.
It'll display The screen like in image.

GridView and ListView in a single fragment

I am doing Android Application for shopping. I need to display products as grid as well as list like this:
https://lh6.ggpht.com/Ly21pAbBRIxAzHn2R119a37NexxtjG5RkQJV8vv0IoCywzksIhKNSCkzWikbUnH8bGY=h900-rw
I don't know how to do this using image button or tabs. Can I change layout of the fragment at runtime? Or I have use 2 different fragments? Please help me.

You have multiple options:
Use RecyclerView
Have two different fragments
Have two different layouts
Use a Framelayout and switch visibility of sub views
Use a ViewFlipper or ViewSwitcher

Why use two layouts when you can simply use RecyclerView and use an imagebutton to handle the clicks and when clicked you can use something like this
// The number of Columns
mLayoutManager = new GridLayoutManager(this, 2);
mRecyclerView.setLayoutManager(mLayoutManager);
and when the listbutton is clicked you can use something like this:
mLayoutManager = new LinearLayoutManager(this);
mRecyclerView.setLayoutManager(mLayoutManager);
I'm not sure whether it would work or not, its just an example,If you want to learn more about implementing girds and lists using RecyclerView and CardView, check out these tutorials I made:
Custom Android lists with CardView and RecyclerView
Custom Android Grids with Images and Texts using RecyclerView

Just look at this:
