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

使用AndroidX,我们将获得一种惊人的显示/隐藏键盘的方法。阅读发行说明-1.5.0-alpha02。现在如何隐藏/显示键盘

val controller = view.windowInsetsController

// Show the keyboard
controller.show(Type.ime())
// Hide the keyboard
controller.hide(Type.ime())

there are two ways to do so...

method 1:in manifest file

define the line **android:windowSoftInputMode="adjustPan|stateAlwaysHidden"** of code in your manifest.xml file as below...

<activity
            android:name="packagename.youactivityname"
            android:screenOrientation="portrait"
            android:windowSoftInputMode="adjustPan|stateAlwaysHidden" />

Method 2 : in Activity or Java class

 if(getCurrentFocus()!=null) {
            InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE)`enter code here`;
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }

它会work....@ASK

protected void hideSoftKeyboard(EditText input) {
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(input.getWindowToken(), 0);    
}

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()

请在onCreate()中尝试以下代码

EditText edtView = (EditText) findViewById(R.id.editTextConvertValue);
edtView.setInputType(InputType.TYPE_NULL);

我创建了一个布局,部分来自xml,部分来自自定义布局引擎,所有这些都在代码中处理。对我来说,唯一有效的方法是跟踪键盘是否打开,并使用如下键盘切换方法:

public class MyActivity extends Activity
{
    /** This maintains true if the keyboard is open. Otherwise, it is false. */
    private boolean isKeyboardOpen = false;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        LayoutInflater inflater;
        inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View contentView = inflater.inflate(context.getResources().getIdentifier("main", "layout", getPackageName()), null);

        setContentView(contentView);
        contentView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() 
        {
            public void onGlobalLayout() 
            {
                Rect r = new Rect();
                contentView.getWindowVisibleDisplayFrame(r);
                int heightDiff = contentView.getRootView().getHeight() - (r.bottom - r.top);
                if (heightDiff > 100) 
                    isKeyboardVisible = true;
                else
                    isKeyboardVisible = false;
             });
         }
    }

    public void closeKeyboardIfOpen()
    {
        InputMethodManager imm;
        imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        if (isKeyboardVisible)
            imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
    }   
}
