请帮忙!
我在静态上下文中创建BitmapDrawable时遇到问题。 我正在为学生竞赛创建一个Android应用程序,因为MainActivity类启动了 看起来“脏”(里面有很多代码)我决定创建扩展MainActivity的MainActivityLayout类。基本上我将一些方法(用于设置布局的方法)从MainActivity移动到MainActivityLayout类。问题是resize()方法,我使用BitmapDrawable构造函数“慢慢地烦我”,因为需要引用资源才能正确调整位图大小。
MainActivity类:
public class MainActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getLayoutOne();
MainActivityLayouts.setLayoutOne();
getLayoutTwo();
MainActivityLayouts.setLayoutTwo();
}
private void getLayoutOne(){
//here I get the layouts id using findViewById() method
}
private void getLayoutTwo(){
//here I get the layout 2 id using findViewById() method
}
protected static Drawable resize(Drawable image,int xSize,int ySize) {
Bitmap b = ((BitmapDrawable)image).getBitmap();
Bitmap bitmapResized = Bitmap.createScaledBitmap(b, xSize, ySize, false);
return new BitmapDrawable(getResources(),bitmapResized);
}
}
MainActivityLayout类:
public class MainActivityLayouts extends MainActivity{
public MainActivityLayouts(){
// ...
}
protected final static void setLayoutOne(){
Drawable drawableOne = ImageViewOne.getDrawable();
//here is the problem...cannot make a static refference...
//getResources() from resize method from MainActivity to be more specific
drawableOne = resize(drawableOne,100,100);
ImageViewOne.setImageDrawable(drawableOne);
}
protected final static void setLayoutTwo(){
Drawable drawableTwo = ImageViewTwo.getDrawable();
//here is the problem...cannot make a static refference...
//getResources() from resize method from MainActivity to be more specific
drawableTwo = resize(drawableTwo,200,200);
ImageViewTwo.setImageDrawable(drawableTwo);
}
我的问题有解决办法吗?在另一种模式下调整大小,还是可以避免创建BitmapDrawable并仍然获得相同的效果? 任何评论家都非常感激:)。
