setWidth()和setHeight()没反应的问题，onCreate()里面获取控件的高度是0

    editText=(EditText)findViewById(R.id.myEditText);  
    // editText.setHeight(10); //不生效  
    editText.getLayoutParams().height = 100;  

 onCreate()里面获取控件的高度是0 解决办法

    int w = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);    
        int h = View.MeasureSpec.makeMeasureSpec(0,View.MeasureSpec.UNSPECIFIED);    
        imageView.measure(w, h);    
        int height =imageView.getMeasuredHeight();    
        int width =imageView.getMeasuredWidth();
