網(wǎng)上很多人對設(shè)置控件的位置都使用view.setPadding(left, top, right, bottom) ，其實這玩意很差勁，它是設(shè)置自己本身位置的偏移，我們很少需要這種效果，我需要的設(shè)置控件相對屏幕左上角的X 、Y位置。眾里尋他千百度，驀然回首，那人卻在燈火闌珊處！

復(fù)制代碼代碼如下:

 
import android.view.View; 
import android.view.ViewGroup.MarginLayoutParams; 
import android.widget.RelativeLayout; 
/* 
* 獲取、設(shè)置控件信息 
*/ 
public class WidgetController { 
/* 
* 獲取控件寬 
*/ 
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()); 
} 
/* 
* 獲取控件高 
*/ 
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()); 
} 

/* 
* 設(shè)置控件所在的位置X，并且不改變寬高， 
* X為絕對位置，此時Y可能歸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); 
} 
/* 
* 設(shè)置控件所在的位置Y，并且不改變寬高， 
* Y為絕對位置，此時X可能歸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); 
} 
/* 
* 設(shè)置控件所在的位置YY，并且不改變寬高， 
* XY為絕對位置 
*/ 
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); 
} 
}
