Question

我试图强迫软件基板开立,以开展一项活动,并粉碎我想要处理自己的意见而进入的一切,我没有埃迪特提。目前,我已尝试过这项工作,但没有工作。我希望,Prk Keyatto在M.AnswerTextView以下开放(注:它是一份案文,不是EditText)。

    InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    // only will trigger it if no physical keyboard is open
    mgr.showSoftInput(mAnswerTextView, InputMethodManager.SHOW_IMPLICIT);

how do I force the Soft Keyboard open
How do I gab everything that is entered so that I can handle each character. I would like to flush each character from the Soft Keyboard after I have handled it. ie, the user should not be able to enter whole words in the Soft Keyboard.

Answer 1

• 努力建立软板:

((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

然后,你可以使用该守则来关闭关键板:

((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(_pay_box_helper.getWindowToken(), 0);

Answer 2

或许需要有一种令人厌恶的文本领域,以引起关注。不过,你可能有一种看不见或具有透明背景,没有治疗。你们也许需要围绕这种观点的焦点环境来看待。

利用文本Watcher,用,或者如果需要一个晚餐层次的ook,则用既定的OnKeyListener()方法确定主听器。见。

利用这一呼吁,开放软键盘:

((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE))
    .showSoftInput(myEditText, InputMethodManager.SHOW_FORCED);

并结束:

((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE))
    .hideSoftInputFromWindow(myEditText.getWindowToken(), 0);

值得注意的是,这实际上不是建议的,迫使钥匙板开张是一件大事。您的用法实际上要求你在不使用正常的ed子的情况下吸收用户投入,并要求在关键的基础上向用户提供意见,而无需背书?

2. 迫使钥匙板打开旧的我

this.getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);

它为我工作。

Answer 4

Sometimes the other answers won t work.
Here is another way..

它将迫使关键板在活动开始时听取窗口的注意。 on Windowcuscusshanged(>>,它将明确并要求EditText的侧重点,然后确定可识别的软输入模式,并将案文选入方框。如果你要求开展这项活动,那么这项工作就应当始终如一。

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        mEditText.clearFocus();
        mEditText.requestFocus();
        getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);
        mEditText.setSelection(mEditText.getText().toString().length());
    }
}

您可能也有此需要。

mEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.showSoftInput(mEditText, InputMethodManager.SHOW_IMPLICIT);
            }
        }
    });

<><>Edit>: 我也看到,钥匙板没有在封顶的碎片中打开,对这些局势有认识。

如果你想控制活动的软键盘,那么使用该代码:

//create soft keyboard object
InputMethodManager imm = (InputMethodManager)this.getSystemService(INPUT_METHOD_SERVICE);

//1.USE
your_view.setFocusableInTouchMode(true); //Enable touch soft keyboard to this view
//or
your_view.setFocusable(true); //Enable keyboard to this view
imm.showInputMethod(your_view, InputMethodManager.SHOW_IMPLICIT);

//2.USE show keyboard if is hidden or hide if it is shown
imm.toggleSoftInputFromWindow(your_view.getWindowToken(),InputMethodManager.SHOW_IMPLICIT, InputMethodManager.HIDE_IMPLICIT_ONLY);
//or
imm.toggleSoftInputFromWindow(InputMethodManager.SHOW_IMPLICIT, InputMethodManager.HIDE_IMPLICIT_ONLY);

//3.USE (you cannot control imm)
this.getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);

//4.USE (with Dialog)
Dialog d = new Dialog(this, android.R.style.Theme_Panel);
d.getWindow().setTitle(null);
d.setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);
d.setOnKeyListener(keyListener);
d.setCanceledOnTouchOutside(true);
d.setCancelable(true);
d.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
d.show();

//to hide keyboard call:
d.dismiss();
//if you want get soft keyboard visibility call:
d.isShowing();

可悲的是,正如我所希望的那样,没有人为我工作。解决办法似乎是等到完成布局阶段。在以下守则中,我注意到我是如何检查<代码>showKey板方法是否回报TRIUE,以及当我去除全球布局听众时。如果不这样做,它就受到打击和错失。现在看来是完美的。

您需要在以下理想情况下:onResume()。

@Override
public void onResume()
{
    super.onResume();

    ViewTreeObserver vto = txtTaskTitle.getViewTreeObserver();
            vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener()
            {
                @Override
                public void onGlobalLayout()
                {
                    if (txtTaskTitle.requestFocus())
                    {
                        if (showKeyboard(getContext(), txtTaskTitle))
                        {
                            txtTaskTitle.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                        }
                    }
                }
            });
}

public static boolean showKeyboard(Context context, EditText target)
{
        if (context == null || target == null)
        {
            return false;
        }

        InputMethodManager imm = getInputMethodManager(context);

        ((InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(target, InputMethodManager.SHOW_FORCED);

        boolean didShowKeyboard = imm.showSoftInput(target, InputMethodManager.SHOW_FORCED);
        if (!didShowKeyboard)
        {
            didShowKeyboard = ((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(target, InputMethodManager.SHOW_FORCED);
        }
        return didShowKeyboard;
}

edt_searchfilter_searchtext.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus){

            }
        }
    });

www.un.org/Depts/DGACM/index_spanish.htm 在你希望开放键盘时,接下线。

 edt_searchfilter_searchtext.requestFocus();

Answer 8

if(search.getText().toString().trim().isEmpty()) {
    InputMethodManager imm = (InputMethodManager)getSystemService(
              Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(search.getWindowToken(), 0);
}

Answer 9

我进行了测试,这项工作正在进行:

... //to show soft keyboard

imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

. . . .

imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

Answer 10

简而言之,增加两条线路将起到一个药店的作用:

如果使用XML

android:focusable="true"
android:focusableInTouchMode="true"

Java的Else:

view.setFocusableInTouchMode(true);
view.requestFocus();

Answer 11

您可以使用这一键盘。 java族

    import android.content.Context;
    import android.view.View;
    import android.view.inputmethod.InputMethodManager;
    import android.widget.EditText;

    /**

    public class KeyboardHelper {

        public static void hideSoftKeyboard(Context context, View view) {
            if (context == null || view == null) {
                return;
            }

            InputMethodManager imm = (InputMethodManager) context
                    .getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(view.getWindowToken(), 0);

        }


        public static void hideSoftKeyboardForced(Context context, View view) {
            if (context == null) {


  return;
        }

        InputMethodManager imm = (InputMethodManager) context
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromInputMethod(view.getWindowToken(), 0);

    }

    public static void hideSoftKeyboard(Context context, EditText editText) {
        if (context == null) {
            return;
        }
        InputMethodManager imm = (InputMethodManager) context
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(editText.getWindowToken(), InputMethodManager.HIDE_IMPLICIT_ONLY);
    }

    public static void showSoftKeyboard(Context context, EditText editText) {

        if (context == null) {
            return;
        }

        InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
        editText.requestFocus();
    }

    public static void showSoftKeyboardForcefully(Context context, EditText editText) {

        if (context == null) {
            return;
        }

        InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
