Issues related to edit text input type

Question

I am having an edit text which is having input type as number. But after doing a task, if again I click on the edit text the input type is changing to text.

For about a second it will display the input type as number and soon it is automatically changing the edit text's input type to text. Even if I click on the keys nothing gets displayed on the edit text.

I checked logcat and I am getting this:

12-20 00:03:09.747: I/Choreographer(5638): Skipped 308 frames!  The application may be doing too much work on its main thread.
12-19 23:57:39.917: W/IInputConnectionWrapper(5638): getTextBeforeCursor on inactive InputConnection
12-20 00:02:45.917: I/InputAttributes(412): InputType.TYPE_NULL is specified

I check this link: getExtractedText on inactive InputConnection warning on android

But unable to find a solution. It will be helpful if someone can help me to solve this issue.

This is my custom cell xml(This edit text is in a listview):

Issue occurs after clicking the mExpiryDate. On click event of mExpiryDate makes a layout which is in gone visibility state to visible state.

Answer 1

This solved the issue:

android:descendantFocusability="afterDescendants"

I added the above code to listview in xml and it solved the issue.

Answer 2

From the line Skipped 308 frames! The application may be doing too much work on its main thread.

Your error shows that you are doing some time consuming tasks on your Main UI thread of your application which requires much time and it blocks the UI.

Try to use the following strategies in order to improve your app performance:

• Use multi-threading programming if possible. The performance benefits are huge, even if your smart phone has one core (threads can run in different cores, if the processor has two or more). It's useful to make your app logic separated from the UI. Use Java threads, AsyncTask or IntentService. Check this.
• Read and follow the misc performance tips of Android development website. Check here.

Also check out Thread

Answer 3

I think your state of listview is not managed on scroll.

    mName.setTypeface(sTfFont);
    mAddress.setTypeface(sTfFont);
    mPolicyNum.setTypeface(sTfFont);
    mNaic.setTypeface(sTfFont);
    mExpiryDate.setTypeface(sTfFont);

did you check by putting it into that if(null==convertView) block, you should check by initializing these same fields inside that block only.

    mName=holder.getName();
    mAddress=holder.getAddress();
    mPolicyNum=holder.getPolicyNum();
    mNaic=holder.getNaic();
    mExpiryDate=holder.getExpiryDate();
    mImgCameraImage=holder.getImgCameraImage();

**Note: Alter Solution : I faced similar issue in dynamic listview but I had a spinner in each list item and what I did is, I removed holder logic and tightly bound ArrayList values with fields and it worked for me though it made scrolling little slower.

Answer 4

try using this in your xml. It might help you, by disabling buttons other than digits and if you want to add some more buttons.

android:digits="0123456789"
