[Solved] Android + Show Imageview fullscreen for 3 seconds and then return to the corresponding activity [closed]

by


You can make one activity in which you can declare one methode which is called on after 3 second and write finish(); in that And in this activity you can pass image name to show in full screen via intent.putExtra

Let me know if you need code

Here is code

  • In *Activity A* save the file (Internal Storage)
String fileName = "SomeName.png";
try {
    FileOutputStream fileOutStream = openFileOutput(fileName, MODE_PRIVATE);
    fileOutStream.write(b);  //b is byte array 
                             //(used if you have your picture downloaded
                             // from the *Web* or got it from the *devices camera*)
                             //otherwise this technique is useless
    fileOutStream.close();
} catch (IOException ioe) {
    ioe.printStackTrace();
}
  • Pass location as String to Activity B
Intent intent = new Intent(this, ActivityB.class);
intent.putExtra("picname", fileName);
  • In *Activity B* retrieve the file
Bundle extras = getIntent().getExtras();
String fileName = extras.getString("picname");
  • Make *drawable* out of the picture
File filePath = getFileStreamPath(fileName);
Drawable d = Drawable.createFromPath(filePath.toString());
  • Apply it to the ImageView resource
someImageView.setBackgroundDrawable(d);

To acces drawable folder resources with name you can use this methode 

private void showImage() {
    String uri = "drawable/icon";

    // int imageResource = R.drawable.icon;
    int imageResource = getResources().getIdentifier(uri, null, getPackageName());

    ImageView imageView = (ImageView) findViewById(R.id.myImageView);
    Drawable image = getResources().getDrawable(imageResource);
    imageView.setImageDrawable(image);
}
