我表示一个输入框使用 AlertDialog.的 EditText 内部对话本身是自动的重点时,我呼叫 AlertDialog.show(), 但软键盘是不会自动显示。

我怎么做软键盘的自动显示当的对话框所示的?(并且没有物理/硬件键盘)。类似于如何,当我按下搜索键援引的全球搜索软键盘是自动地图所示。

有帮助吗?

解决方案

您可以创建在EditTextAlertDialog一个焦点侦听器,然后拿到AlertDialogWindow。从那里,你可以通过调用setSoftInputMode软键盘显示。

final AlertDialog dialog = ...;

editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
        }
    }
});

其他提示

有关表示键盘使用:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

有关隐藏键盘使用:

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

-

可以创建(R20上SDK测试)的对话框之后请求软键盘

// create dialog
final AlertDialog dialog = ...; 

// request keyboard   
dialog.getWindow().setSoftInputMode (WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

我有同样的问题,并用下面的代码来解决它。我不知道它会如何表现与硬件键盘的手机上。

// TextEdit
final EditText textEdit = new EditText(this);

// Builder
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Enter text");
alert.setView(textEdit);

alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        String text = textEdit.getText().toString();
        finish();
    }
});

alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        finish();
    }
});

// Dialog
AlertDialog dialog = alert.create();
dialog.setOnShowListener(new OnShowListener() {

    @Override
    public void onShow(DialogInterface dialog) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(textEdit, InputMethodManager.SHOW_IMPLICIT);
    }
});

dialog.show();

我找到了这个例子 http://android-codes-examples.blogspot.com/2011/11/show-or-hide-soft-keyboard-on-opening.html.添加以下代码之前 alert.show().

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
<activity
    ...
    android:windowSoftInputMode="stateVisible" >
</activity>

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

从其他的答案代码片段工作,但它并不总是显而易见的地方放置它们的代码,特别是如果你使用的是AlertDialog.Builder跟着的官对话框教程因为它不使用或final AlertDialog ... alertDialog.show()

alertDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

优选的是

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

由于如果焦点从EditText上,其中SHOW_FORCED将保持显示的键盘,直到它被明确地驳回开关远,即使用户返回到主屏幕或显示最近使用的应用SOFT_INPUT_STATE_ALWAYS_VISIBLE将隐藏键盘。

用于AlertDialog下面是工作的代码使用具有定义在XML中一个EditText自定义布局创建。它还设置键盘有一个“走出去”的关键,并允许它触发肯定按钮。

alert_dialog.xml:

<RelativeLayout
android:id="@+id/dialogRelativeLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >

    <!-- android:imeOptions="actionGo" sets the keyboard to have a "go" key instead of a "new line" key. -->
    <!-- android:inputType="textUri" disables spell check in the EditText and changes the "go" key from a check mark to an arrow. -->
    <EditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="16dp"
        android:layout_marginLeft="4dp"
        android:layout_marginRight="4dp"
        android:layout_marginBottom="16dp"

        // onCreateDialog requires the return of an AlertDialog.
        return alertDialog;
    }
}

那么,这是一个很老的文章,还有什么要补充的结果,这些是2种简单的方法,帮助我保持键盘得到控制,他们的工作只是完美的:

显示键盘

public void showKeyboard() {
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    View v = getCurrentFocus();
    if (v != null)
        imm.showSoftInput(v, 0);
}

<强>隐藏键盘

public void hideKeyboard() {
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    View v = getCurrentFocus();
    if (v != null)
        imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}

让我指出一些额外的信息,以欲哭的解决方案,因为我发现它很难得到这个工作!我如何从我的AlertDialog.Builder的AlertDialog对象?嗯,这是我的alert.show()执行的结果是:

final AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
final EditText input = new EditText(getActivity());
alert.setView(input);

// do what you need, like setting positive and negative buttons...

final AlertDialog dialog = alert.show();

input.setOnFocusChangeListener(new OnFocusChangeListener() {
   @Override
   public void onFocusChange(View v, boolean hasFocus) {
      if(hasFocus) {
         dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
      }
   }
});

看看 讨论处理手动隐藏和显示IME。然而,我的感觉是,如果一个集中 EditText 是不是把IME它是因为你打电话 AlertDialog.show() 在你 OnCreate() 或者一些其他的方法是诱发之前的屏幕上实际介绍。移动它 OnPostResume() 应该修复它在这种情况下,我认为。

是的,你可以用setOnFocusChangeListener做它会帮助你。

editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus) {
            dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
        }
    }
});

如果任何人是获得:

  
    

不能使从类型活动的静态参照非静态方法getSystemService(字符串)

  

尝试添加的上下文以getSystemService呼叫。

所以

InputMethodManager imm = 
(InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

在原始的问题涉及对话框和我的EditText是定期视图。总之,我怀疑这应该对大多数的你工作了。因此,这里对我来说是什么在起作用(上述建议的收视率最高的方法,什么也没做对我来说)。下面是执行此操作的自定义EditView中(子类是没有必要的,但我发现它方便了我的目的,我想也抢焦点,当视图变得可见)。

这实际上是主要由于tidbecks回答相同。我居然没有注意到他的回答都因为它实现了零选票。然后,我正要只是评论他的岗位,但它已经太长时间,所以我最终反正做这个职位。 tidbeck指出,他不清楚它如何与有键盘的设备的工作原理。我可以确认的行为似乎是在两种情况下完全相同。这是这样的,在人像模式中,软件键盘被弹出和景观事实并非如此。具有物理键盘滑出或不使我的手机上没有任何区别。

由于,我个人发现有点笨拙我选择使用的行为:InputMethodManager.SHOW_FORCED。这个工程,我想它的工作。无论方位的键盘变得可见,但是,至少我的设备上,如果硬件键盘已经滑出它不会弹出。

import android.app.Service;
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;

public class BringOutTheSoftInputOnFocusEditTextView extends EditText {

    protected InputMethodManager inputMethodManager;

    public BringOutTheSoftInputOnFocusEditTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    public BringOutTheSoftInputOnFocusEditTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public BringOutTheSoftInputOnFocusEditTextView(Context context) {
        super(context);
        init();
    }

    private void init() {
        this.inputMethodManager = (InputMethodManager)getContext().getSystemService(Service.INPUT_METHOD_SERVICE);
        this.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    BringOutTheSoftInputOnFocusEditTextView.this.inputMethodManager.showSoftInput(BringOutTheSoftInputOnFocusEditTextView.this, InputMethodManager.SHOW_FORCED);
                }
            }
        });
    }

    @Override
    protected void onVisibilityChanged(View changedView, int visibility) {
        super.onVisibilityChanged(changedView, visibility);
        if (visibility == View.VISIBLE) {
            BringOutTheSoftInputOnFocusEditTextView.this.requestFocus();
        }
    }

}

这个问题似乎是因为在那里你输入文字最初是隐藏(或嵌套或东西),AlertDialog自动设置标志WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IMWindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,这样的事情不会触发软输入露面的地方。

这解决这个问题的方法是添加以下内容:

(...)
// Create the dialog and show it
Dialog dialog = builder.create()
dialog.show();

// After show (this is important specially if you have a list, a pager or other view that uses a adapter), clear the flags and set the soft input mode
dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

尝试与使用:

editText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);

把这些方法在你的Util类,并在任何地方使用。

    val view = activity.currentFocus
    val methodManager = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager

为什么这个答案-因为上面的解决方案将展示你的键盘,但它不会消失,如果你击其他任何地方, EditText.所以你需要做些什么来使键盘消失的时候 EditText 失去了焦点。

你可以实现这种通过以下步骤:

  1. 使父母查看(内容的看您的活动)和可点击的焦通过添加下列属性

        android:clickable="true" 
        android:focusableInTouchMode="true" 
    
  2. 实现hideKeyboard()方法

        public void hideKeyboard(View view) {
            InputMethodManager inputMethodManager =(InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(),InputMethodManager.HIDE_IMPLICIT_ONLY );
        }
    
  3. 最后,设置onFocusChangeListener你edittext.

        edittext.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (!hasFocus) {
                    hideKeyboard(v);
                }
            }
        });
    

这是有点复杂。我没有用这种方式和它的工作。

1.At第一呼叫隐藏从窗口软输入。这将隐藏软输入,如果软键盘是可见的或者什么也不做,如果它不是。

2.Show你的对话框

3.Then只需调用切换软输入。

代码:

InputMethodManager inputManager = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); 
//hiding soft input
inputManager.hideSoftInputFromWindow(findViewById(android.R.id.content).getWind‌​owToken(), 0);
//show dialog
yourDialog.show();
//toggle soft input
inputManager.toggleSoftInput(InputMethodManager.SHOW_FORCED,InputMethodManager.SHOW_IMPLICIT);

尝试此

  

SomeUtils.java

public static void showKeyboard(Activity activity, boolean show) {
    InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);

    if(show)
        inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
    else
        inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY,0);
}

试了很多,但是这对我来说(科特林)什么工作:

        val dialog = builder.create()
        dialog.setOnShowListener {
            nameEditText.requestFocus()
            val s = ContextCompat.getSystemService(requireContext(), InputMethodManager::class.java)
            s?.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0)
        }

        dialog.setOnDismissListener {
            val s = ContextCompat.getSystemService(requireContext(), InputMethodManager::class.java)
            s?.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0)
        }

        dialog.show()

综观 https://stackoverflow.com/a/39144104/2914140 我简化了一下:

// In onCreateView():
view.edit_text.run {
    requestFocus()
    post { showKeyboard(this) }
}

fun showKeyboard(view: View) {
    val imm = view.context.getSystemService(
        Context.INPUT_METHOD_SERVICE) as InputMethodManager?
    imm?.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
}

它比 https://stackoverflow.com/a/11155404/2914140 更好:

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

因为当你按下Home键,并移动到主屏幕,键盘将保持打开。

我知道这个问题是旧的,我认为使用扩展功能是显示键盘编辑文本更漂亮的方式

这里是我使用来显示键盘一个EditText的方法。

<强>科特林代码: 只需要调用edittext.showKeyboard()

fun EditText.showKeyboard() {
  post {
    requestFocus()
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT)
  }
}

<强> java代码:

public static void showKeyboard(EditText editText) {
    editText.post(new Runnable() {
      @Override
      public void run() {
        editText.requestFocus();
        InputMethodManager imm = (InputMethodManager) editText.getContext()
            .getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
      }
    });
  }
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

我把这种在的onCreate()来自动显示键盘,当我在活动
