问题
In my application, the device soft-keyboard is covering the EditTextViews, so user cannot see what he is typing.
So i want to hide other Views(like a button in my case), to make the EditTextViews visible.
But instead on doing something like
EditText.onFocus(){
//hide button
}
for every EditText, i want to do something like
if(soft-keyboard.isOpenned())
//hide button
}
how to track if soft-keyboard is openned or closed?
Edit:
Actually my layout is this:

The problem comes when i am typing text in the EditTextViews in the ScrollView
回答1:
There is no direct way to find it, but i come up with a dirty solution and it work fine. The idea behind is to compare the height of two views your activity and keyboard.
boolean watcherState;
private void isShowing() {
final RelativeLayout relative = (RelativeLayout) findViewById(R.id.parent);
relative.getViewTreeObserver().addOnGlobalLayoutListener(
new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
// r will be populated with the coordinates of your view
// that area still visible.
relative.getWindowVisibleDisplayFrame(r);
int heightDiff = relative.getRootView().getHeight()
- (r.bottom - r.top);
Log.d("Height", heightDiff + "//");
if (heightDiff > 100) { // if more than 100 pixels, its
// probably a keyboard...
watcherState = true;
} else
watcherState = false;
}
});
}

You should probably use android:windowSoftInputMode attribute in the manifest file to describe how the screen layout should arrange when soft keyboard shows up (http://developer.android.com/guide/topics/manifest/activity-element.html#wsoft)
android:windowSoftInputMode="adjustResize":
The activity's main window is always resized to make room for the soft keyboard on screen.
android:windowSoftInputMode="adjustPan"
The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.
回答3:
For handling softkepad detection, set the android:ConfigChanges attribute for your activity in the AndroidManifest.xml file:
<activity android:name="com.myapp.MyActivity"
android:label="@string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation"
>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Here, the keyboard|keyboardHidden flag in android:configChanges tells the system that the Activity wishes to invoke the onConfigurationChanged() method of your Activity instead, which allow you to handle the softkebaord changes.
Here’s an example onConfigurationChanged() which replaces the main content view for the currently running Activity:
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Set a new layout - framework will automatically choose portrait or landscape as needed
setContentView( R.layout.my_activity_layout );
// Reconnect all listeners for controls in the layout
a.findViewById( R.id.exit_button ).setOnClickListener( mListener );
}
Odds are, your onConfigurationChanged() method will need to do almost exactly the same kind of work as your Activity’s onCreate() method, so it’s probably a good idea to DRY out your code by factoring out your layout setup into a separate helper method that you invoke from both onCreate() and onConfigurationChanged().
