Android - Keyboard not appearing in floating window

问题

I'm writing an application that uses the following code to draw an edittext on the screen over running applications:

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_PHONE,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE
                    | WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
                PixelFormat.TRANSLUCENT);

windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

windowManager.addView(mEditText, params);

The xml for the edittext is:

<EditText
            android:id="@+id/mEditText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:maxLines="3"
            android:inputType="textAutoComplete|text"
            android:focusable="true"
            android:focusableInTouchMode="true" />

However focusing on this does not bring up the keyboard. I've also tried programmatically bringing it up with an onFocusListener:

mEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if(hasFocus) {
                    Log.d("", "Has focus");
                    ((InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
                } else {
                    Log.d("", "Lost focus");
                }
            }
        });

But although that is called, as seen from the logcat, nothing happens. The only method I've found so far to display the keyboard is using:

getSystemService(Context.INPUT_METHOD_SERVICE)).toggleSoftInput(0, 0);

But that seems to type onto the screen and not into the edittext. I've also tried clear focusable when the edittext is displayed but to no avail.

I'm guessing the issue is because I'm using a "floating window" but there must be a way to make this work as apps such as floating calculators exist on the playstore which take input.. Anyone have any ideas? I'm stumped :(

My bad.. I realized if I remove the WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE it works fine.. silly mistake

回答2:

Use WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                    WindowManager.LayoutParams.WRAP_CONTENT,
                    WindowManager.LayoutParams.WRAP_CONTENT,
                    WindowManager.LayoutParams.TYPE_PHONE,
                    WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL,
                    PixelFormat.TRANSLUCENT);

i resolved this issue by using FLAG_NOT_FOCUSABLE

回答4:

Programatically:

editText.requestFocus();

Or through XML:

<EditText...>
    <requestFocus />
</EditText>
