How can I set the minimum length? 回答1: A little hackish , but you can put your EditText inside a FrameLayout alongside with another TextView with text="0000" and

问题 Basically, I want an EditText in Android where I can have an integer value entered into. Perhaps there is a more appropriate object than EditText for this? 回答1: For now, use an EditText . Use android:inputType="number" to force it to be numeric. Convert the resulting string into an integer (e.g., Integer.parseInt(myEditText.getText().toString()) ).

问题 I want to have 5 lines for the height of the text area. I am using the following code. <EditText android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:singleLine="false" android:lines="5" android:layout_marginLeft="10dip" android:layout_marginRight="10dip" /> The text area looks fine, but the problem is that the cursor is blinking in the middle of the text field.

问题 I have a numberDecimal EditText which I want to validate using a regular expression. In validation what I want is: Before the decimal point, the maximum digit I want to enter is three and the digit should not start with zero like 2,23,342 , etc. After the decimal point, the maximum digit I want to enter is one like .1 , .3 , .6 , etc. So the number that I allow the user to enter is like 2.1 , 32.5 , 444.8 , 564.9 , etc. But in my code, what happens is: It allows the user to enter more than a

问题 I found this old post which definitely helps with my problem, but I'm noticing that it doesn't really seem to solve my problem.
