Android weird display behaviour with soft keyboard

Question

I click a button and launch an activity with a soft keyboard:

When I click on the Cancel button, it calls finish() to exit to the first page. Then when I launch the activity again i get this:

The layout with the buttons is now hidden behind the keyboard.

In another scenario if i do it this way:

1. Launch activity.
2. Click back button to dismiss keyboard.
3. Click back button to go to first page.
4. Launch activity.

I get picture 1. The buttons don't get hidden. Seems like I have to destroy the keyboard before calling finish().

How do I solve this problem?

Edit: Added example of what's in the Manifest

 <activity            
        android:name=".SignUp"
        android:theme="@style/DefaultTitle" />

This is in my manifest as well, I added it after reading some other posts, didn't work for me.

<uses-sdk
    android:minSdkVersion="4"
    android:targetSdkVersion="7" />

Ok LOL. Weird discovery. If I do this:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(cancel.getApplicationWindowToken(), 0);
            try {
                Thread.sleep(100);
            } catch (Exception e) {                 
            }
            finish();

it works! Not sure if this is a good workaround....

Answer 1

Put this line in your activity tag and let me know what happen,

<activity android:windowSoftInputMode="stateVisible" . . . >

For more info look at android:windowSoftInputMode

Answer 2

I think you are showing the SoftKeyBoard Using STATE_ALWAYS_VISIBLE Thats Why it remain visible when you comes back to the activity.

So Try to open keyboard on Button Click this way..

EditText editText = (EditText) findViewById(R.id.myEdit);
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
// only will trigger it if no physical keyboard is open
mgr.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

And if there are any windowSoftInputMode in Manifest,Remove them cause will not need them for above method.

尝试在edittext的对象上使用setfocus方法
