提问by user3737339
How to increase or decrease the size of imageview,textview or anyother by programmatically in linear layout in getview() of slide menu.
如何在滑动菜单的 getview() 中以线性布局以编程方式增加或减少 imageview、textview 或任何其他的大小。
I got slide menu through androidhive tutorials
我通过 androidhive 教程获得了幻灯片菜单
Exactly in slide menu I need to add a user profile pic and his name ,location as like in facebook,google and other social sites for this tried a lot with (getlayoutparams(),setheight()...) even though with a lot of method but I can't set it in side menu list.
正是在幻灯片菜单中，我需要添加用户个人资料图片和他的姓名，就像在 facebook、google 和其他社交网站中一样，为此尝试了很多 (getlayoutparams(),setheight()...) 即使有很多方法，但我无法在侧菜单列表中设置它。
What ever method but no changes in the profile pic and name.
有什么方法，但个人资料图片和名称没有变化。
Here is my code:
这是我的代码：

Layout:
布局：
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
If anyone have have idea about this please guide me friends.

To Set Width and Height Programmetically and make sure that you have not given fixed width and height to the parent layout of imageview
以编程方式设置宽度和高度并确保您没有为 imageview 的父布局提供固定的宽度和高度
android.view.ViewGroup.LayoutParams layoutParams = imageView.getLayoutParams();
layoutParams.width = 80;
layoutParams.height = 80;
imageView.setLayoutParams(layoutParams);

This simple way to do your task:
这种完成任务的简单方法：
setContentView(R.id.main);
ImageView iv = (ImageView) findViewById(R.id.left);
int width = 60;
int height = 60;
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(width,height);
iv.setLayoutParams(parms);
and another way if you want to give screen size in height and width then use below code :
和另一种方式，如果你想在高度和宽度上给出屏幕尺寸，然后使用下面的代码：
setContentView(R.id.main);
Display display = getWindowManager().getDefaultDisplay();
ImageView iv = (ImageView) findViewById(R.id.left);
int width = display.getWidth(); // ((display.getWidth()*20)/100)
int height = display.getHeight();// ((display.getHeight()*30)/100)
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(width,height);
iv.setLayoutParams(parms);
hope use full to you.
希望对你充分利用。

Perhaps you could try setting the minHeight of the parent container (the LinearLayout in your case) to the height you would like for the image and set the height to WRAP_CONTENT?
也许您可以尝试将父容器（在您的情况下为 LinearLayout）的 minHeight 设置为您想要的图像高度并将高度设置为 WRAP_CONTENT？
