以编程方式设置可绘制的大小 [英] Set drawable size programmatically

问题描述

图像（图标）的大小大致相同，但我需要调整大小以使按钮保持相同的高度。

The images (icons) come in roughly the same size, but I need to resize them in order for the buttons to remain the same height.

我如何这样做？

Button button = new Button(this);
button.setText(apiEventObject.getTitle());
button.setOnClickListener(listener);

/*
 * set clickable id of button to actual event id
 */
int id = Integer.parseInt(apiEventObject.getId());
button.setId(id);

button.setLayoutParams(new LayoutParams(
        android.view.ViewGroup.LayoutParams.FILL_PARENT,
        android.view.ViewGroup.LayoutParams.WRAP_CONTENT));

Drawable drawable = LoadImageFromWebOperations(apiSizeObject.getSmall());
//?resize drawable here? drawable.setBounds(50, 50, 50, 50);
button.setCompoundDrawablesWithIntrinsicBounds(drawable, null, null, null);

推荐答案

setBounds（）方法对每种类型的容器都不起作用（但是对我的某些 ImageView 有效）。

The setBounds() method doesn't work for every type of container (did work for some of my ImageView's, however).

尝试以下方法来缩放drawable本身：

Try the method below to scale the drawable itself:

// Read your drawable from somewhere
Drawable dr = getResources().getDrawable(R.drawable.somedrawable);
Bitmap bitmap = ((BitmapDrawable) dr).getBitmap();
// Scale it to 50 x 50
Drawable d = new BitmapDrawable(getResources(), Bitmap.createScaledBitmap(bitmap, 50, 50, true));
// Set your new, scaled drawable "d"
