textView not display output

Question

I'm building apps that detect color when 'imageview' is clicked. Unfortunately, after I get rid all the warning at 'getResource().getContent()',the output did not display. or my 'if' is wrong? perhaps someone can help me :)

Button button;
ImageView imageView;
static final int CAM_REQUEST = 1;
TextView  colorRGB;
Context context = this;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.capimg);



    colorRGB = (TextView)findViewById(R.id.colorrgb);
    button = (Button) findViewById(R.id.button);
    imageView = (ImageView) findViewById(R.id.image_view);



    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            Intent camera_intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            File file = getFile();
            camera_intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
            startActivityForResult(camera_intent, CAM_REQUEST);





        }
    });






    imageView.setOnTouchListener(imgSourceOnTouchListener);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){

    String path = "sdcard/UTP_app/cam_image.jpg";
    imageView.setImageDrawable(Drawable.createFromPath(path));

}



private File getFile() {
    File folder = new File("sdcard/UTP_app");
    if (!folder.exists()) {
        folder.mkdir();
    }

    File image_file = new File(folder,"cam_image.jpg");
    return image_file;
    //return new File(folder, new Date().getTime()+".jpg");
}


OnTouchListener imgSourceOnTouchListener
        = new OnTouchListener(){

    @Override
    public boolean onTouch(View view, MotionEvent event) {

You're setting text for your rgb TextView from string.xml so you should change

colorRGB.setText(R.string.blue_colour);

to

colorRGB.setText(getResources().getString(R.string.blue_colour));

Hope this help

Definitely yes ! You are using If wrongly, You are initializing value of x

int x = 0;

And checking

if(x < 0)

Which always returns false.

Zaidi Over a year ago

should I initialize x as 1? sorry i'm newbie

Zaidi Over a year ago

changed but still have the same problem

Shree Krishna Over a year ago

There may be other kind of problem too, You have to find out them... And don't use neither 0 nor 1 use if(x < bitmap.getWidth()-1). As your statements.

Shree Krishna Over a year ago

Change your statements too as Phan Văn Linh answered.
