Closing keyboard programmatically not working on Android 10

问题

我已在我的API 19真实设备和API 23模拟器上进行了测试,这种方法效果很好:

if(activity != null){
            View view = activity.getCurrentFocus();
            if (view != null){
                InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
                if(inputManager != null){
                    inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
                }
            }
        }

然而,在我的Pixel 4a(安卓10)真实设备上无法正常工作。有人知道如何在安卓10上以编程方式关闭键盘吗?

英文:

I've tested it on my API 19 real device and API 23 emulator and this method works fine:

if(activity != null){
            View view = activity.getCurrentFocus();
            if (view != null){
                InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
                if(inputManager != null){
                    inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
                }
            }
        }

However, it's not working on my Pixel 4a (android 10) real device. Does anyone know how to close the keyboard programmatically on android 10?

基于您所处的情况,您可以使用以下方法之一:

boolean hideSuccess = KeyboardUtils.hideKeyboard(activity);

// 或者
boolean hideSuccess = KeyboardUtils.hideKeyboard(fragment);

// 或者
boolean hideSuccess = KeyboardUtils.hideKeyboard(editText); // 推荐使用

KeyboardUtils.java

import android.app.Activity;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;

import androidx.fragment.app.Fragment;

public class KeyboardUtils {

    public static boolean hideKeyboard(Activity activity) {
        InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
        if (imm != null) {
            View focus = activity.getCurrentFocus();
            if (focus == null) focus = new View(activity);
            return imm.hideSoftInputFromWindow(focus.getWindowToken(), 0);
        } else {
            return false;
        }
    }

    public static boolean hideKeyboard(Fragment fragment) {
        InputMethodManager imm = (InputMethodManager) fragment.requireContext().getSystemService(Activity.INPUT_METHOD_SERVICE);
        if (imm != null) {
            View focus = fragment.requireActivity().getCurrentFocus();
            if (focus == null) focus = new View(fragment.requireContext());
            return imm.hideSoftInputFromWindow(focus.getWindowToken(), 0);
        } else {
            return false;
        }
    }

    public static boolean hideKeyboard(EditText editText) {
        InputMethodManager imm = (InputMethodManager) editText.getContext().getSystemService(Activity.INPUT_METHOD_SERVICE);
        if (imm != null) {
            return imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
        } else {
            return false;
        }
    }
}

Based on where you are, you can use one of the below methods:

boolean hideSuccess = KeyboardUtils.hideKeyboard(activity);
// or
boolean hideSuccess = KeyboardUtils.hideKeyboard(fragment);
// or
boolean hideSuccess = KeyboardUtils.hideKeyboard(editText); // It's recommended

KeyboardUtils.java

import android.app.Activity;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;
import androidx.fragment.app.Fragment;
/**

public class KeyboardUtils {
public static boolean hideKeyboard(Activity activity) {
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
if (imm != null) {
View focus = activity.getCurrentFocus();
if (focus == null) focus = new View(activity);
return imm.hideSoftInputFromWindow(focus.getWindowToken(), 0);
} else {
return false;
}
}
public static boolean hideKeyboard(Fragment fragment) {
InputMethodManager imm = (InputMethodManager) fragment.requireContext().getSystemService(Activity.INPUT_METHOD_SERVICE);
if (imm != null) {
View focus = fragment.requireActivity().getCurrentFocus();
if (focus == null) focus = new View(fragment.requireContext());
return imm.hideSoftInputFromWindow(focus.getWindowToken(), 0);
} else {
return false;
}
}
public static boolean hideKeyboard(EditText editText) {
InputMethodManager imm = (InputMethodManager) editText.getContext().getSystemService(Activity.INPUT_METHOD_SERVICE);
if (imm != null) {
return imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
} else {
return false;
}
}
}

尝试以下静态方法:

public static void hideSoftKeyboard(Activity activity) {

    InputMethodManager inputMethodManager =
            (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);

    View currentFocus = activity.getCurrentFocus();

    if (inputMethodManager != null) {
        IBinder windowToken = activity.getWindow().getDecorView().getRootView().getWindowToken();
        inputMethodManager.hideSoftInputFromWindow(windowToken, 0);
        inputMethodManager.hideSoftInputFromWindow(windowToken, InputMethodManager.HIDE_NOT_ALWAYS);

        if (currentFocus != null) {
            inputMethodManager.hideSoftInputFromWindow(currentFocus.getWindowToken(), 0);
        }
    }

}
英文:

Try the below static method

public static void hideSoftKeyboard(Activity activity) {
InputMethodManager inputMethodManager =
(InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
View currentFocus = activity.getCurrentFocus();
if (inputMethodManager != null) {
IBinder windowToken = activity.getWindow().getDecorView().getRootView().getWindowToken();
inputMethodManager.hideSoftInputFromWindow(windowToken, 0);
inputMethodManager.hideSoftInputFromWindow(windowToken, InputMethodManager.HIDE_NOT_ALWAYS);
if (currentFocus != null) {
inputMethodManager.hideSoftInputFromWindow(currentFocus.getWindowToken(), 0);
}
}
}

在您的清单中添加任务权限。

<uses-permission android:name="android.permission.GET_TASKS"/>
英文:

Add the task permission on your manifest.

&lt;uses-permission android:name=&quot;android.permission.GET_TASKS&quot;/&gt;
