프로그래밍 방식으로 ImageView 표시

프로그래밍 방식으로 ImageView 표시

---

사용자가 버튼을 클릭 할 때 화면 중앙에 ImageView를 표시하려면 어떻게해야합니까? res / drawable-folder에 이미지를 배치했습니다.

아래 코드로 시도했지만 ImageView를 표시하는 방법을 모르겠습니다.

 View v = new ImageView(getBaseContext());
 ImageView image; 
 image = new ImageView(v.getContext()); 
 image.setImageDrawable(v.getResources().getDrawable(R.drawable.gameover));

감사!

• ImageView 만들기
• 버튼에서 OnClickListener 사용
• 레이아웃에 ImageView를 추가 하거나 ImageView 의 가시성 을 VISIBLE로 설정합니다.

//LinearLayOut Setup
LinearLayout linearLayout= new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);

linearLayout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT));

//ImageView Setup
ImageView imageView = new ImageView(this);

//setting image resource
imageView.setImageResource(R.drawable.play);

//setting image position
imageView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, 
LayoutParams.WRAP_CONTENT));

//adding view to layout
linearLayout.addView(imageView);
//make visible to program
setContentView(linearLayout);

int id = getResources().getIdentifier("gameover", "drawable", getPackageName());
ImageView imageView = new ImageView(this);
LinearLayout.LayoutParams vp = 
    new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                    LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(vp);        
imageView.setImageResource(id);        
someLinearLayout.addView(imageView);

RelativeLayout에 추가하는 경우 imageView의 위치를 ​​설정하는 것을 잊지 마십시오. 예를 들면 :

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(200, 200);
lp.addRule(RelativeLayout.CENTER_IN_PARENT); // A position in layout.
ImageView imageView = new ImageView(this); // initialize ImageView
imageView.setLayoutParams(lp);
// imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
imageView.setImageResource(R.drawable.photo);
RelativeLayout layout = (RelativeLayout) findViewById(R.id.layout);
layout.addView(imageView);
