android在代碼中設置控件的長和高

這裏介紹LinearLayout和RelativeLayout兩種佈局下的控件

LinearLayout.LayoutParams paramss = (LinearLayout.LayoutParams) imageview.getLayoutParams();
        paramss.height = 100;//設置佈局的高度
        paramss.weight = 100;//設置佈局寬度
        layout_1.setLayoutParams(paramss);//將設置好的佈局參數應用到控件中

RelativeLayout.LayoutParams params2 = (RelativeLayout.LayoutParams) imageview.getLayoutParams();
        params2.width = 100;//設置佈局寬度
        params2.height = 100;//設置佈局的高度
        iv_left.setLayoutParams(params2);

這兩種佈局稍微有點區別
