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);    
}

如果你在.xml android中设置:focused=“true”,那么他就不会工作,因为这是一个不可更改的设置。

因此解决方案:android:focusedByDefault=“true”

比他设置一次,可以隐藏/显示键盘

添加到Manifest文件中的活动android:windowSoftInputMode=“stateHidden”。例子:

<activity
            android:name=".ui.activity.MainActivity"
            android:label="@string/mainactivity"
            android:windowSoftInputMode="stateHidden"/>
public final class UtilsKeyboard {
/**
 * Sets the cursor at the end of this edit text and shows a keyboard
 */
public static void focusKeyboard(@NonNull EditText editText) {
    editText.requestFocus();
    editText.setSelection(editText.getText().length());
    showKeyboard(editText);
}

private static void showKeyboard(@NonNull View view) {
    final InputMethodManager manager = (InputMethodManager) view.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
    if (manager != null) {
        manager.showSoftInput(view, InputMethodManager.SHOW_FORCED);
    }
}

public static boolean hideKeyboard(@NonNull Window window) {
    View view = window.getCurrentFocus();
    return hideKeyboard(window, view);
}

private static boolean hideKeyboard(@NonNull Window window, @Nullable View view) {
    if (view == null) {
        return false;
    }
    InputMethodManager inputMethodManager = (InputMethodManager) window.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
    if (inputMethodManager != null) {
        return inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
    return false;
}

public static boolean hideKeyboard(@Nullable View view) {
    if (view == null) {
        return false;
    }
    InputMethodManager inputMethodManager = (InputMethodManager) view.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
    if (inputMethodManager != null) {
        return inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }
    return false;
}

/**
 * This will hide the keyboard and unfocus any focused view.
 */
public static void unfocusKeyboard(@NonNull Window window) {
    // When showing the bottom menu, make sure the keyboard isn't and that no view has focus
    hideKeyboard(window);
    final View focused = window.getCurrentFocus();
    if (focused != null) focused.clearFocus();
}}

您也可以使用此代码段在Kotlin中隐藏键盘。

 fun hideKeyboard(activity: Activity?) {
    val inputManager: InputMethodManager? = 
    activity?.getSystemService(Context.INPUT_METHOD_SERVICE) as? 
    InputMethodManager
    // check if no view has focus:
    val v = activity?.currentFocus ?: return
    inputManager?.hideSoftInputFromWindow(v.windowToken, 0)
 }

简单易用的方法,只需调用hideKeyboardFrom(YourActivity.this);隐藏键盘

/**
 * This method is used to hide keyboard
 * @param activity
 */
public static void hideKeyboardFrom(Activity activity) {
    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
