推荐答案
重新考虑您的设计并为您的用户提供令人愉悦的体验.
Rethink your design and provide a delightful experience for your users.
您需要关注Android设备中的某些可变性领域，以及这些变化如何影响Android应用程序的开发和设计.
You need to focus on some areas of variability in Android devices and how those variations affect the development and design of Android applications.
- 布局位置
- 大小，填充和边距
- 通用布局
- 资源限定符
- 拆分视图
结论:
如果您要使用一种屏幕布局，则不要使用带有权重的线性布局. 官方示例:
if Your Are Concerning with one screen layout than use linear layout with weights. OFFICIAL Example:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:orientation="vertical" >
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/to" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/subject" />
<EditText
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:gravity="top"
android:hint="@string/message" />
<Button
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:text="@string/send" />
否则将可滚动的布局(如listview卡视图)与每行的realitivelayout一起使用，因为这样可以更有效地进行布局.
else use scroll-able layouts like listview card view with realitivelayout for each row because it is more efficiently.
P.S.您在xml中设置了很多不必要的属性..我只是在几秒钟内完成了此操作，以帮助您.您应该阅读RelativeLayout和LinearLayout的工作方式. 有关更多知识，请阅读官方文件
P.S. You have a lot of unnecessary atributes set in xml.. I just did this in a few sec to help you. You should read how RelativeLayout and LinearLayout work. For More knowledge read official documents
