我正在使用以下方法從Drawables動態創建Bitmaps並將它們賦給我的ImageViews。這種方法被重複調用。問題是，我無法正確設置圖像的大小，在不同的手機上它看起來不同，在我的Note 3上看起來很大，在我的朋友銀河核心上它看起來很小。動態設置ImageView的大小Android
方法
public void setImageView(int i,Integer d, LinearLayout layout) {
ImageView imageView = new ImageView(this);
imageView.setId(i);
imageView.setPadding(2, 2, 2, 2);
imageView.setMaxHeight(200);
imageView.setMaxWidth(200);
imageView.setAdjustViewBounds(true);
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
parms.setMargins(15, 50, 15, 25);
imageView.setLayoutParams(parms);
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
imageView.setImageBitmap(BitmapFactory.decodeResource(getResources(), d));
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
layout.addView(imageView);
}
方法
的使用horizontal_scroll.setVisibility(View.VISIBLE);
LinearLayout layout = (LinearLayout) findViewById(R.id.scroll_view_layout);
setImageView(1, R.drawable.hex_filled, layout);
setImageView(2, R.drawable.hex_filled, layout);
setImageView(3, R.drawable.hex_filled, layout);
setImageView(4, R.drawable.hex_filled, layout);
setImageView(5, R.drawable.hex_filled, layout);
setImageView(6, R.drawable.hex_filled, layout);
setImageView(7, R.drawable.hex_filled, layout);
