Hide keypad in android while touching outside Edit Text Area
提问by Nithin Michael
I know that the code for dismiss tyhe keypad in android is
我知道在 android 中关闭 tyhe 键盘的代码是
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);
Can anyone suggest me a method to hide the keypad if we touch the area outside the text area other than the keypad in the screen.
如果我们触摸屏幕中键盘以外的文本区域之外的区域，任何人都可以向我建议一种隐藏键盘的方法。

Code to dismiss Softkeyboard is below:
关闭软键盘的代码如下：
public static void hideSoftKeyboard(Activity activity) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
You can put it in Utility Class or if you are defining it within an activity, avoid the activity parameter, or call hideSoftKeyboard(this).
您可以将它放在实用程序类中，或者如果您在活动中定义它，请避免使用活动参数，或调用 hideSoftKeyboard(this)。
You can write a method that iterates through every View in your activity, and check if it is an instanceof EditText if it is not register a setOnTouchListener to that component and everything will fall in place. In case you are wondering how to do that, it is in fact quite simple. Here is what you do, you write a recursive method like the following.
您可以编写一个方法来遍历活动中的每个视图，并检查它是否是 EditText 的实例，如果它没有向该组件注册 setOnTouchListener 并且一切都会就位。如果您想知道如何做到这一点，实际上很简单。这就是你要做的，你写一个递归方法，如下所示。
public void setupUI(View view) {
//Set up touch listener for non-text box views to hide keyboard.
if(!(view instanceof EditText)) {
view.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
hideSoftKeyboard();
return false;
}
});
}
//If a layout container, iterate over children and seed recursion.
if (view instanceof ViewGroup) {
for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
View innerView = ((ViewGroup) view).getChildAt(i);
setupUI(innerView);
}
}
}
Call this method after SetcontentView()with paramet as idof your view like:
在您的视图中SetcontentView()使用参数调用此方法，id例如：
RelativeLayoutPanel android:id="@+id/parent"> ... </RelativeLayout>
Then call setupUI(findViewById(R.id.parent))
然后打电话 setupUI(findViewById(R.id.parent))

Best way you can useis DONE button besides EditTextmake your onClickListenerto do like,
除了 EditText 之外，您可以使用的最佳方法是DONE 按钮，让您的onClickListener这样做，
done.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);
}
});

This may be old but I got this working by implenting a custom class
这可能很旧，但我通过实施自定义类来实现这一目标
public class DismissKeyboardListener implements OnClickListener {
Activity mAct;
public DismissKeyboardListener(Activity act) {
this.mAct = act;
}
@Override
public void onClick(View v) {
if ( v instanceof ViewGroup ) {
hideSoftKeyboard( this.mAct );
}
}
}
public void hideSoftKeyboard(Activity activity) {
InputMethodManager imm = (InputMethodManager)
getSystemService(Activity.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
}
the best practice here is to create a Helper class and every container Relative / Linear Layouts should implement this.
这里的最佳实践是创建一个 Helper 类，并且每个容器相对 / 线性布局都应该实现这一点。
**** Take note only the main Container should implement this class (For optimization) ****
**** 注意只有主容器应该实现这个类（为了优化）****
and implement it like this :
并像这样实现它：
Parent.setOnClickListener( new DismissKeyboardListener(this) );
the keyword this is for Activity. so if you are on fragment you use it like getActivity();
关键字 this 是针对 Activity 的。所以如果你在片段上，你可以像 getActivity() 一样使用它；
