Android: Learning Notes (i)

Some of the problems that you encounter in Android learning are recorded.

1, solve the problem of edittext exclamation.
This text field does not specify an inputtype or a hint

Add the following code to resolve:

android:hint="@null"

2, solve android4.0 after the EditText border is not full display problem

android:background="@android:drawable/edit_text"

把android:password="true"改动为android:inputType="textPassword"
