获取控件大小和设置调整控件的位置XY示例

网上很多人对设置控件的位置都使用view.setPadding(left, top, right, bottom) ，其实这玩意很差劲，它是设置自己本身位置的偏移，我们很少需要这种效果，我需要的设置控件相对屏幕左上角的X 、Y位置。众里寻他千百度，蓦然回首，那人却在灯火阑珊处！
复制代码 代码如下:
import android.view.View;
import android.view.ViewGroup.MarginLayoutParams;
import android.widget.RelativeLayout;

public class WidgetController {

public static int getWidth(View view)
{
int w = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
int h = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
view.measure(w, h);
return (view.getMeasuredWidth());
}

public static int getHeight(View view)
{
int w = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
int h = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);
view.measure(w, h);
return (view.getMeasuredHeight());
}


public static void setLayoutX(View view,int x)
{
MarginLayoutParams margin=new MarginLayoutParams(view.getLayoutParams());
margin.setMargins(x,margin.topMargin, x+margin.width, margin.bottomMargin);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(margin);
view.setLayoutParams(layoutParams);
}

public static void setLayoutY(View view,int y)
{
MarginLayoutParams margin=new MarginLayoutParams(view.getLayoutParams());
margin.setMargins(margin.leftMargin,y, margin.rightMargin, y+margin.height);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(margin);
view.setLayoutParams(layoutParams);
}

public static void setLayout(View view,int x,int y)
{
MarginLayoutParams margin=new MarginLayoutParams(view.getLayoutParams());
margin.setMargins(x,y, x+margin.width, y+margin.height);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(margin);
view.setLayoutParams(layoutParams);
}
}
