Answer 1

Through the warning, the system just wants to say you have the space to optimize your layout code.There is no need to care much about it if you do not want to optimize your code now.

Answer 2

If are looking for layout as below then the xml is as follows

<?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:orientation="horizontal" 
    android:gravity="center">
<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Password" />
<EditText
        android:layout_marginLeft="5dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="Password" />


</LinearLayout>

Answer 3

Remove the TableLayout tags and put the attributes into the TableRow tags.

Answer 4

Why do you need top most LinearLayout when you dont have anything inside LinearLayout except TableLayout? One of these layout should be enough. Remove either LinearLayout (or) TableLayout. That should resolve the issue.
