問題描述

我正在編寫一個應(yīng)用程序，它使用以下代碼在正在運(yùn)行的應(yīng)用程序的屏幕上繪制編輯文本:

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);

edittext的xml是:

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" />

但是，專注于此并不會調(diào)出鍵盤.我還嘗試通過 onFocusListener 以編程方式提出它:

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");
                }
            }
        });

但是，從 logcat 中可以看出，盡管調(diào)用了它，但什么也沒發(fā)生.到目前為止，我發(fā)現(xiàn)顯示鍵盤的唯一方法是使用:

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);

但這似乎是在屏幕上輸入而不是在編輯文本中.當(dāng)顯示編輯文本時，我也嘗試過清晰可聚焦，但無濟(jì)于事.

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.

我猜這個問題是因?yàn)槲沂褂玫氖歉哟翱?，但必須有一種方法可以使這項(xiàng)工作成為可能，因?yàn)?Playstore 中存在浮動計(jì)算器等應(yīng)用程序，它們需要輸入.有人有什么想法嗎?我被難住了:(

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 :(

推薦答案

我的錯.. 我意識到如果我刪除 WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE 它可以正常工作.. 愚蠢的錯誤

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