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

如果要使用Java代码隐藏键盘,请使用以下命令:

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

或者,如果您希望始终隐藏键盘,请在AndroidManifest中使用此选项:

 <activity
 android:name=".activities.MyActivity"
 android:configChanges="keyboardHidden"  />

其他回答

如果这里的所有其他答案都不适合您,那么还有另一种手动控制键盘的方法。

创建一个用于管理EditText的某些财产的函数:

public void setEditTextFocus(boolean isFocused) {
    searchEditText.setCursorVisible(isFocused);
    searchEditText.setFocusable(isFocused);
    searchEditText.setFocusableInTouchMode(isFocused);

    if (isFocused) {
        searchEditText.requestFocus();
    }
}

然后,确保在EditText的焦点上打开/关闭键盘:

searchEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (v == searchEditText) {
            if (hasFocus) {
                // Open keyboard
                ((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(searchEditText, InputMethodManager.SHOW_FORCED);
            } else {
                // Close keyboard
                ((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(searchEditText.getWindowToken(), 0);
            }
        }
    }
});

现在,每当您想要打开键盘时,请手动调用:

setEditTextFocus(true);

对于结束通话:

setEditTextFocus(false);

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);

添加到Manifest文件中的活动android:windowSoftInputMode=“stateHidden”。例子:

<activity
            android:name=".ui.activity.MainActivity"
            android:label="@string/mainactivity"
            android:windowSoftInputMode="stateHidden"/>
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”

这对我有用:

 @Override
 public boolean dispatchTouchEvent(MotionEvent event) {
View v = getCurrentFocus();
boolean ret = super.dispatchTouchEvent(event);

if (v instanceof EditText) {
    View w = getCurrentFocus();
    int scrcoords[] = new int[2];
    w.getLocationOnScreen(scrcoords);
    float x = event.getRawX() + w.getLeft() - scrcoords[0];
    float y = event.getRawY() + w.getTop() - scrcoords[1];

    Log.d("Activity",
            "Touch event " + event.getRawX() + "," + event.getRawY()
                    + " " + x + "," + y + " rect " + w.getLeft() + ","
                    + w.getTop() + "," + w.getRight() + ","
                    + w.getBottom() + " coords " + scrcoords[0] + ","
                    + scrcoords[1]);
    if (event.getAction() == MotionEvent.ACTION_UP
            && (x < w.getLeft() || x >= w.getRight() || y < w.getTop() || y > w
                    .getBottom())) {

        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(getWindow().getCurrentFocus()
                .getWindowToken(), 0);
    }
}
return ret;
}
