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);    
}

在如此的搜索中,我找到了一个适合我的答案

// Show soft-keyboard:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

// Hide soft-keyboard:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

您还可以研究在EditText上使用setImeOption。

我只是遇到了一个非常模拟的情况,我的布局包含一个EditText和一个搜索按钮。当我发现我可以在editText中将time选项设置为“actionSearch”时,我意识到我甚至不再需要搜索按钮。软键盘(在此模式下)有一个搜索图标,可用于启动搜索(键盘会自动关闭)。

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();
}}
 //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);
        }
```

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)
    }
