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：

  1. if(activity != null){
  2.             View view = activity.getCurrentFocus();
  3.             if (view != null){
  4.                 InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
  5.                 if(inputManager != null){
  6.                     inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
  7.                 }
  8.             }
  9.         }

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:

  1. if(activity != null){
  2.             View view = activity.getCurrentFocus();
  3.             if (view != null){
  4.                 InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
  5.                 if(inputManager != null){
  6.                     inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
  7.                 }
  8.             }
  9.         }

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：

  1. boolean hideSuccess = KeyboardUtils.hideKeyboard(activity);
  3. // 或者
  4. boolean hideSuccess = KeyboardUtils.hideKeyboard(fragment);
  6. // 或者
  7. boolean hideSuccess = KeyboardUtils.hideKeyboard(editText); // 推荐使用

KeyboardUtils.java

  1. import android.app.Activity;
  2. import android.view.View;
  3. import android.view.inputmethod.InputMethodManager;
  4. import android.widget.EditText;
  6. import androidx.fragment.app.Fragment;
  8. public class KeyboardUtils {
  10.     public static boolean hideKeyboard(Activity activity) {
  11.         InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
  12.         if (imm != null) {
  13.             View focus = activity.getCurrentFocus();
  14.             if (focus == null) focus = new View(activity);
  15.             return imm.hideSoftInputFromWindow(focus.getWindowToken(), 0);
  16.         } else {
  17.             return false;
  18.         }
  19.     }
  21.     public static boolean hideKeyboard(Fragment fragment) {
  22.         InputMethodManager imm = (InputMethodManager) fragment.requireContext().getSystemService(Activity.INPUT_METHOD_SERVICE);
  23.         if (imm != null) {
  24.             View focus = fragment.requireActivity().getCurrentFocus();
  25.             if (focus == null) focus = new View(fragment.requireContext());
  26.             return imm.hideSoftInputFromWindow(focus.getWindowToken(), 0);
  27.         } else {
  28.             return false;
  29.         }
  30.     }
  32.     public static boolean hideKeyboard(EditText editText) {
  33.         InputMethodManager imm = (InputMethodManager) editText.getContext().getSystemService(Activity.INPUT_METHOD_SERVICE);
  34.         if (imm != null) {
  35.             return imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
  36.         } else {
  37.             return false;
  38.         }
  39.     }
  40. }

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

  1. boolean hideSuccess = KeyboardUtils.hideKeyboard(activity);
  2. // or
  3. boolean hideSuccess = KeyboardUtils.hideKeyboard(fragment);
  4. // or
  5. boolean hideSuccess = KeyboardUtils.hideKeyboard(editText); // It's recommended

KeyboardUtils.java

  1. import android.app.Activity;
  2. import android.view.View;
  3. import android.view.inputmethod.InputMethodManager;
  4. import android.widget.EditText;
  5. import androidx.fragment.app.Fragment;
  6. /**

  8. */
  9. public class KeyboardUtils {
  10. public static boolean hideKeyboard(Activity activity) {
  11. InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
  12. if (imm != null) {
  13. View focus = activity.getCurrentFocus();
  14. if (focus == null) focus = new View(activity);
  15. return imm.hideSoftInputFromWindow(focus.getWindowToken(), 0);
  16. } else {
  17. return false;
  18. }
  19. }
  20. public static boolean hideKeyboard(Fragment fragment) {
  21. InputMethodManager imm = (InputMethodManager) fragment.requireContext().getSystemService(Activity.INPUT_METHOD_SERVICE);
  22. if (imm != null) {
  23. View focus = fragment.requireActivity().getCurrentFocus();
  24. if (focus == null) focus = new View(fragment.requireContext());
  25. return imm.hideSoftInputFromWindow(focus.getWindowToken(), 0);
  26. } else {
  27. return false;
  28. }
  29. }
  30. public static boolean hideKeyboard(EditText editText) {
  31. InputMethodManager imm = (InputMethodManager) editText.getContext().getSystemService(Activity.INPUT_METHOD_SERVICE);
  32. if (imm != null) {
  33. return imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
  34. } else {
  35. return false;
  36. }

尝试以下静态方法：

  1. public static void hideSoftKeyboard(Activity activity) {
  3.     InputMethodManager inputMethodManager =
  4.             (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
  6.     View currentFocus = activity.getCurrentFocus();
  8.     if (inputMethodManager != null) {
  9.         IBinder windowToken = activity.getWindow().getDecorView().getRootView().getWindowToken();
  10.         inputMethodManager.hideSoftInputFromWindow(windowToken, 0);
  11.         inputMethodManager.hideSoftInputFromWindow(windowToken, InputMethodManager.HIDE_NOT_ALWAYS);
  13.         if (currentFocus != null) {
  14.             inputMethodManager.hideSoftInputFromWindow(currentFocus.getWindowToken(), 0);
  15.         }
  16.     }
  18. }
英文:

Try the below static method

  1. public static void hideSoftKeyboard(Activity activity) {
  2. InputMethodManager inputMethodManager =
  3. (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
  4. View currentFocus = activity.getCurrentFocus();
  5. if (inputMethodManager != null) {
  6. IBinder windowToken = activity.getWindow().getDecorView().getRootView().getWindowToken();
  7. inputMethodManager.hideSoftInputFromWindow(windowToken, 0);
  8. inputMethodManager.hideSoftInputFromWindow(windowToken, InputMethodManager.HIDE_NOT_ALWAYS);
  9. if (currentFocus != null) {
  10. inputMethodManager.hideSoftInputFromWindow(currentFocus.getWindowToken(), 0);
  11. }
  12. }
  13. }

在您的清单中添加任务权限。

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