我设置的可绘制的进度对话框（ pbarDialog ），但我的问题是，我希望每次调整的绘制，但无法弄清楚如何。

下面是一些code：

 处理程序progressHandler =新的处理程序（）{

    公共无效的handleMessage（信息MSG）{
        开关（msg.what）{
            //一些code
            案例UPDATE_PBAR：
                pbarDialog.setIcon（mAppIcon）;
                pbarDialog.setMessage（mPbarMsg）;
                pbarDialog.incrementProgressBy（mIncrement + 1）;
                打破;
        }
    }
};

pbarDialog.show（）;

螺纹myThread =新主题（新的Runnable（）{

    公共无效的run（）{
        //一些code
        的for（int i = 0; I＆LT; mApps.size（）;我++）{
            。mAppIcon = mAdapter.getIcons（）得到（mApps.get（ⅰ）.getPackageName（））;
            //这里需要调整绘制
            progressHandler.sendEmptyMessage（UPDATE_PBAR）;
        }
        handler.sendEmptyMessage（DISMISS_PBAR）;
    }

}）;

myThread.start（）;
 

解决方案

对我下面的工作：

 私人绘​​制对象调整大小（绘制的图像）{
    位图B =（（BitmapDrawable）图像）.getBitmap（）;
    位图bitma presized = Bitmap.createScaledBitmap（B，50，50，FALSE）;
    返回新BitmapDrawable（getResources（），bitma presized）;
}
 

I am setting a drawable for a progress dialog (pbarDialog) but my issue is I want to resize the drawable each time but can't figure out how.

Here is some code:

Handler progressHandler = new Handler() {

    public void handleMessage(Message msg) {
        switch (msg.what) {
            // some more code
            case UPDATE_PBAR:
                pbarDialog.setIcon(mAppIcon);
                pbarDialog.setMessage(mPbarMsg);
                pbarDialog.incrementProgressBy(mIncrement+1);
                break;
        }
    }
};

pbarDialog.show();

Thread myThread = new Thread(new Runnable() {

    public void run() {
        // some code
        for (int i = 0; i < mApps.size(); i++) {
            mAppIcon = mAdapter.getIcons().get(mApps.get(i).getPackageName());
            // need to resize drawable here
            progressHandler.sendEmptyMessage(UPDATE_PBAR);
        }
        handler.sendEmptyMessage(DISMISS_PBAR);
    }

});

myThread.start();

The following worked for me:

private Drawable resize(Drawable image) {
    Bitmap b = ((BitmapDrawable)image).getBitmap();
    Bitmap bitmapResized = Bitmap.createScaledBitmap(b, 50, 50, false);
    return new BitmapDrawable(getResources(), bitmapResized);
}
