    Intent configIntent = new Intent(WidgetActivity1_1.this,UpdateWidgetService.class);
    configIntent.putExtra("Appid", appWidgetId);

您可以通过以下方式设置布局参数:

myImageView.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));

或者设置一个数字.

图像大小操作有时可能很棘手,建议首先获取图像布局参数,更改它并将其设置回来:

android.view.ViewGroup.LayoutParams layoutParams = myImageView.getLayoutParams();
layoutParams.width = 30;
layoutParams.height = 30;
myImageView.setLayoutParams(layoutParams);

如果你还有问题需要改变它的大小,试着将它放在LinearLayout中并使用布局参数操作imageView大小:

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(30, 30);
myImageView.setLayoutParams(layoutParams);
