Verify if EditText is at visible positon in screen

Question

This problem I am going to introduce, only happen in Android 4.0 +
I have a LinearLayout with 4 TableLayout, it's parent is a ScrollView. I add TableRows dynamically into each TableLayout.

My TableRows are like this.

<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tableRow1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/borda"
    android:layout_margin="10dip"
    android:paddingLeft="10dip"
    >
  <LinearLayout
    android:id="@+id/l1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_marginTop="15dip"
    android:layout_marginBottom="15dip"
    >

    <TextView
        android:id="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/nome"
        android:textStyle="bold"
        android:textColor="#526691"
        android:textSize="15sp"
        android:paddingLeft="10dip"
        android:paddingRight="5dip"
         />


       <EditText
        android:id="@+id/valorLabel"
        android:layout_width="140dip"
        android:layout_height="wrap_content"
        android:textSize="15sp" 
        android:background="#ffffffff"   
        android:singleLine="true"   
        android:inputType="textCapSentences" 
         android:textColor="#777777" />          


 </LinearLayout>

</TableRow>

It seems to have a problem when the focused EditText is scrolled to out of the screen.

Question How can I know if the EditText is visible in the screen? Is there a way of remove focus in the EditText if it's parent is scrolled?

Second Question
Why my TableRow's background get white when EditText is focused ?

To answer your first question `yourEditText.getVisibility() == View.VISIBLE)` will `return true` if it is `Visible`. What is the problem it is giving you? — codeMagic, May 03 '13 at 19:52

here is the answer of the first question: Android: how to check if a View inside of ScrollView is visible?

second one, you can set OnTouchListener on the parent view. When scrolled, its x or y value changes, then do clearFocus() on the EditText. Here is a good reference, check the Touch Event Listener part: http://www.techotopia.com/index.php/Android_Touch_and_Multi-touch_Event_Handling

If you put your source code and the error log, you would get much better specific answer.

Actually there are many EditText's, no one of them can be focused outside the screen, otherwise the screen will flash(blink). Your solution worked in parts. I am clearing the focus of all EditText, but sometimes, it's still flashing. And when the EditText is focused, the TableRow's background gets white. @tjPark – Renaro Santos May 03 '13 at 21:53
