延迟将图片保存在图库中

Question

Wassup Guys, i'm doing a college project, and my app is a meme generator. After the text plotted, i'm trying to save the image pushing the button. The toast appears, but, it takes more than an hour to the pic show on the gallery. How can i make this thing save immediately?

So there are my codes to create the button listener and the store function

    save.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View view){
            View content  = findViewById(R.id.lay);
            Bitmap bitmap = getScreenShot(content);
            currentImage = "meme" + System.currentTimeMillis() + ".png";
            store(bitmap, currentImage);
            share.setEnabled(true);
        }

    });




    public void store(Bitmap bm, String fileName){
    String dirPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Memes";
    File dir  = new File(dirPath);
    if(!dir.exists()){
        dir.mkdir();
    }
    File file = new File(dirPath, fileName);
    try{
        FileOutputStream fos = new FileOutputStream(file);
        bm.compress(Bitmap.CompressFormat.PNG, 100, fos);
        fos.flush();
        fos.close();
        Toast.makeText(this, "SALVOU ARROMBADO", Toast.LENGTH_SHORT).show();
    }catch (Exception e){
        Toast.makeText(this, "DEU RUIM VACILÃO", Toast.LENGTH_SHORT).show();
    }
}

You have to use MediaScannerConnection like below .Create a method refreshMedia() -

public void refreshMedia(){

 new Handler().postDelayed(new Runnable() {
  @Override
  public void run() {
    MediaScannerConnection.scanFile(ApplicationContext.context, new String[] { imageFile.getPath() }, null,
              new MediaScannerConnection.OnScanCompletedListener() {
                @Override
                public void onScanCompleted(String path, Uri uri) {
                //gallery refreshed.
                  Log.i(TAG, "Scanned " + path);
                }
              });
           }
        }, 1500);  //this is to refresh media after 1.5 second delay

}

Here imageFile.getPath() is path for your image.

Use it as below-

save.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View view){

             store(bitmap, currentImage);
            //after saving image call refreshmedia()
             refreshMedia();
        }
