// final AlertDialog dialog = new AlertDialog.Builder(this).create();
// ImageView imgView = getView();
// dialog.setView(imgView);
// dialog.show();
// 全屏显示的方法
final Dialog dialog = new Dialog(this, android.R.style.Theme_Black_NoTitleBar_Fullscreen);
ImageView imgView = getView();
dialog.setContentView(imgView);
dialog.show();
// 点击图片消失
imgView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.dismiss();
}
});
}
private ImageView getView() {
ImageView imgView = new ImageView(this);
imgView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
InputStream is = getResources().openRawResource(R.drawable.thumbnail);
Drawable drawable = BitmapDrawable.createFromStream(is, null);
imgView.setImageDrawable(drawable);
return imgView;
}
