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?

这对我很有用

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    if (imm.isActive())
        imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);

其他回答

public static void closeInput(final View caller) {  
    caller.postDelayed(new Runnable() {
        @Override
        public void run() {
            InputMethodManager imm = (InputMethodManager) caller.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(caller.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }, 100);
}

此方法通常有效,但有一个条件:不能设置android:windowSoftInputMode=“any_of_themes”

当您想手动隐藏键盘时,单击按钮:

/**
 * Hides the already popped up keyboard from the screen.
 *
 */
public void hideKeyboard() {
    try {
        // use application level context to avoid unnecessary leaks.
        InputMethodManager inputManager = (InputMethodManager) getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        assert inputManager != null;
        inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

当您想在屏幕上除编辑文本以外的任何地方隐藏键盘时在活动中重写此方法:

@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    View view = getCurrentFocus();
    if (view != null && (ev.getAction() == MotionEvent.ACTION_UP || ev.getAction() == MotionEvent.ACTION_MOVE) && view instanceof EditText && !view.getClass().getName().startsWith("android.webkit.")) {
        int scrcoords[] = new int[2];
        view.getLocationOnScreen(scrcoords);
        float x = ev.getRawX() + view.getLeft() - scrcoords[0];
        float y = ev.getRawY() + view.getTop() - scrcoords[1];
        if (x < view.getLeft() || x > view.getRight() || y < view.getTop() || y > view.getBottom())
            ((InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow((this.getWindow().getDecorView().getApplicationWindowToken()), 0);
    }
    return super.dispatchTouchEvent(ev);
}

对于那些寻找喷气背包的人来说,写下答案。

val keyboardController = LocalSoftwareKeyboardController.current

//for showing the keyboard
keyboardController?.show()
//for hiding the keyboard
keyboardController?.hide()

我的解决方案:

用活动构造它(视图是可选的),使用处理程序发布它(有一些延迟,例如100ms更好)。直接调用输入管理器有时不起作用。只有在工作时才能获得“活动”。我认为这很正常。

如果您可以在通话时获取根视图组或编辑视图,只需发送它即可获得更好的结果。

public class CloseSoftKeyboardRunnable implements Runnable
{
    Activity activity;
    View view;  // for dialog will occur context getcurrentfocus == null. send a rootview to find currentfocus.

    public CloseSoftKeyboardRunnable(Activity activity, View view)
    {
        this.activity = activity;
        this.view = view;
    }

    public CloseSoftKeyboardRunnable(Activity activity)
    {
        this.activity = activity;
    }
    @Override
    public void run() {
        if (!activity.isFinishing())
        {
            InputMethodManager imm = (InputMethodManager)activity.getSystemService(Context.INPUT_METHOD_SERVICE);

            if (view == null) {
                view = activity.getCurrentFocus();
            }
            else
            {
                try {
                    view = ((ViewGroup)view).getFocusedChild();
                }
                catch ( Exception e) {}
            }

            Window window =  activity.getWindow();
            
            if (window != null)
            {
                if (view == null) {
                    try {
                        view = window.getDecorView();
                        view = ((ViewGroup)view).getFocusedChild();
                    }
                    catch ( Exception e) {}
                }

                if (view == null) {
                    view = window.getDecorView();
                }

                if (view != null) {
                    if (view instanceof EditText)
                    {
                        EditText edittext = ((EditText) view);
                        edittext.setText(edittext.getText().toString()); // reset edit text bug on some keyboards bug
                        edittext.clearFocus();
                    }

                    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
                }
                window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
            }
        }
    }
}

调用此方法以隐藏软键盘

public void hideKeyBoard() {
    View view1 = this.getCurrentFocus();
    if(view!= null){
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view1.getWindowToken(), 0);
    }
}
