代码：
import android.view.View;import android.view.ViewGroup.MarginLayoutParams;import android.widget.RelativeLayout;/* * 获取、设置控件信息 */public class WidgetController {/* * 获取控件宽 */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());       }/* * 获取控件高 */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());       }/* * 设置控件所在的位置X，并且不改变宽高， * X为绝对位置，此时Y可能归0 */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);}/* * 设置控件所在的位置Y，并且不改变宽高， * Y为绝对位置，此时X可能归0 */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);}/* * 设置控件所在的位置YY，并且不改变宽高， * XY为绝对位置 */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);}}
