Пробую 4-я способами программно вставить картинку в ImageView, но ничего не выходит.
В чем моя ошибка или чего здесь не хватает?Javapublic class MainActivity extends AppCompatActivity {
ImageView img1,img2,img3,img4;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img1 = (ImageView) findViewById(R.id.img1);
img2 = (ImageView) findViewById(R.id.img2);
img3 = (ImageView) findViewById(R.id.img3);
img4 = (ImageView) findViewById(R.id.img4);
//setResource
// if(img1 != null) img1.setImageResource(R.drawable.china); //Dropped
//setDrawable
img2.setImageDrawable(Drawable.createFromPath("/res/drawable/tokyo1.png"));
//setBitmap
img3.setImageBitmap(BitmapFactory.decodeResource(this.getResources(), R.drawable.tokyo2));
//Picasso(local)
Picasso.get()
.load(R.drawable.tokyo1)
.into(img4);
//Picasso(URI)
Picasso.get()
.load("https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTmG5K1tMdQ4W3G1WlZSfSWfL6jo8E9rS4NTHflXoT1CsF2Na_i")
.into(img1);
}
}
