我的布局中有一个EditText和一个Button。

在编辑字段中写入并单击按钮后,我想在触摸键盘外部时隐藏虚拟键盘。我假设这是一段简单的代码,但我在哪里可以找到它的示例?


当前回答

protected void hideSoftKeyboard(EditText input) {
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(input.getWindowToken(), 0);    
}

 //In Activity
        View v = this.getCurrentFocus();
        if (v != null) {
            InputMethodManager im = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
            im.hideSoftInputFromWindow(view.getWindowToken(), 0);
        }


//In Fragment
        View v = getActivity().getCurrentFocus();
        if (v != null) {
            InputMethodManager im = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
            im.hideSoftInputFromWindow(view.getWindowToken(), 0);
        }
```

Android 11中有一个名为WindowInsetsController的新API,应用程序可以从任何视图访问控制器,通过它我们可以使用hide()和show()方法

val controller = view.windowInsetsController

// Show the keyboard (IME)
controller.show(Type.ime())

// Hide the keyboard
controller.hide(Type.ime())

看见https://developer.android.com/reference/android/view/WindowInsetsController

there are two ways to do so...

method 1:in manifest file

define the line **android:windowSoftInputMode="adjustPan|stateAlwaysHidden"** of code in your manifest.xml file as below...

<activity
            android:name="packagename.youactivityname"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="adjustPan|stateAlwaysHidden" />

Method 2 : in Activity or Java class

 if(getCurrentFocus()!=null) {
            InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE)`enter code here`;
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }

它会work....@ASK

这对我所有奇怪的键盘行为都有效

private boolean isKeyboardVisible() {
    Rect r = new Rect();
    //r will be populated with the coordinates of your view that area still visible.
    mRootView.getWindowVisibleDisplayFrame(r);

    int heightDiff = mRootView.getRootView().getHeight() - (r.bottom - r.top);
    return heightDiff > 100; // if more than 100 pixels, its probably a keyboard...
}

protected void showKeyboard() {
    if (isKeyboardVisible())
        return;
    InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    if (getCurrentFocus() == null) {
        inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    } else {
        View view = getCurrentFocus();
        inputMethodManager.showSoftInput(view, InputMethodManager.SHOW_FORCED);
    }
}

protected void hideKeyboard() {
    if (!isKeyboardVisible())
        return;
    InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    View view = getCurrentFocus();
    if (view == null) {
        if (inputMethodManager.isAcceptingText())
            inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_NOT_ALWAYS, 0);
    } else {
        if (view instanceof EditText)
            ((EditText) view).setText(((EditText) view).getText().toString()); // reset edit text bug on some keyboards bug
        inputMethodManager.hideSoftInputFromInputMethod(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
}

在Kotlin

fun hideKeyboard(activity: BaseActivity) {
        val view = activity.currentFocus?: View(activity)
        val imm = activity.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
        imm.hideSoftInputFromWindow(view.windowToken, 0)
    }
