以编程方式显示ImageView

| 当用户单击按钮时，如何使ImageView出现在屏幕中间？我已将图像放置在res / drawable-folder中。我一直在尝试下面的代码，但是我不知道如何使ImageView出现：

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

谢谢！

创建ImageView 在按钮中使用OnClickListener 将ImageView添加到布局中或将ImageView的可见性设置为VISIBLE

抹持奠糙驰

//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);

如果添加到RelativeLayout，请不要忘记设置imageView的位置。例如：

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);
