Disable keyboard on EditText
提问by Ferox
I'm doing a calculator.
So I made my own Buttonswith numbers and functions.
The expression that has to be calculated, is in an EditText, because I want users can add numbers or functions also in the middle of the expression, so with the EditTextI have the cursor. But I want to disable the Keyboardwhen users click on the EditText.
I found this example that it's ok for Android 2.3, but with ICSdisable the Keyboardand also the cursor.
我在做计算器。所以我Buttons用数字和函数制作了我自己的。必须计算EditText的表达式EditText在cursor. 但是我想Keyboard在用户单击EditText. 我发现这个例子可以用于Android 2.3，但ICS禁用Keyboard和光标。
public class NoImeEditText extends EditText {
public NoImeEditText(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public boolean onCheckIsTextEditor() {
return false;
}
}
And then I use this NoImeEditTextin my XMLfile
然后我NoImeEditText在我的XML文件中使用它
<com.my.package.NoImeEditText
android:id="@+id/etMy"
....
/>
How I can make compatible this EditText with ICS??? Thanks.
我如何使这个 EditText 与 ICS 兼容？？？谢谢。

Hereis a website that will give you what you need
这是一个可以为您提供所需内容的网站
As a summary, it provides links to InputMethodManagerand Viewfrom Android Developers. It will reference to the getWindowTokeninside of Viewand hideSoftInputFromWindow()for InputMethodManager
总而言之，它提供了InputMethodManager与ViewAndroid 开发人员之间的链接。它将引用getWindowToken内部View和hideSoftInputFromWindow()为InputMethodManager
A better answer is given in the link, hope this helps.
链接中给出了更好的答案，希望这会有所帮助。
here is an example to consume the onTouch event:
这是使用 onTouch 事件的示例：
editText_input_field.setOnTouchListener(otl);
private OnTouchListener otl = new OnTouchListener() {
public boolean onTouch (View v, MotionEvent event) {
return true; // the listener has consumed the event
}
};
Here is another example from the same website. This claims to work but seems like a bad idea since your EditBox is NULL it will be no longer an editor:
这是来自同一网站的另一个示例。这声称有效，但似乎是一个坏主意，因为您的 EditBox 为 NULL，它将不再是编辑器：
MyEditor.setOnTouchListener(new OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
int inType = MyEditor.getInputType(); // backup the input type
MyEditor.setInputType(InputType.TYPE_NULL); // disable soft input
MyEditor.onTouchEvent(event); // call native handler
MyEditor.setInputType(inType); // restore input type
return true; // consume touch even
}
});
Hope this points you in the right direction
希望这为您指明了正确的方向

Below code is both for API >= 11 and API < 11. Cursor is still available.
下面的代码适用于 API >= 11 和 API < 11。游标仍然可用。
/**
* Disable soft keyboard from appearing, use in conjunction with android:windowSoftInputMode="stateAlwaysHidden|adjustNothing"
* @param editText
*/
public static void disableSoftInputFromAppearing(EditText editText) {
if (Build.VERSION.SDK_INT >= 11) {
editText.setRawInputType(InputType.TYPE_CLASS_TEXT);
editText.setTextIsSelectable(true);
} else {
editText.setRawInputType(InputType.TYPE_NULL);
editText.setFocusable(true);
}
}

You can also use setShowSoftInputOnFocus(boolean)directly on API 21+ or through reflection on API 14+:
您还可以直接在 API 21+ 上或通过对 API 14+ 的反射使用setShowSoftInputOnFocus(boolean)：
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
editText.setShowSoftInputOnFocus(false);
} else {
try {
final Method method = EditText.class.getMethod(
"setShowSoftInputOnFocus"
, new Class[]{boolean.class});
method.setAccessible(true);
method.invoke(editText, false);
} catch (Exception e) {
// ignore
}
}

Add below properties to the Edittext controller in the layout file
将以下属性添加到布局文件中的 Edittext 控制器
<Edittext
android:focusableInTouchMode="true"
android:cursorVisible="false"
android:focusable="false" />
I have been using this solution for while and it works fine for me.
我一直在使用这个解决方案，它对我来说很好用。

Disable the keyboard (API 11 to current)
禁用键盘（API 11 到当前）
This is the best answer I have found so far to disable the keyboard (and I have seen a lot of them).
这是迄今为止我找到的禁用键盘的最佳答案（我见过很多）。
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { // API 21
editText.setShowSoftInputOnFocus(false);
} else { // API 11-20
editText.setTextIsSelectable(true);
}
There is no need to use reflection or set the InputTypeto null.
无需使用反射或将 设置InputType为 null。
Re-enable the keyboard
重新启用键盘
Here is how you re-enable the keyboard if needed.
如果需要，您可以通过以下方法重新启用键盘。
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { // API 21
editText.setShowSoftInputOnFocus(true);
} else { // API 11-20
editText.setTextIsSelectable(false);
editText.setFocusable(true);
editText.setFocusableInTouchMode(true);
editText.setClickable(true);
editText.setLongClickable(true);
editText.setMovementMethod(ArrowKeyMovementMethod.getInstance());
editText.setText(editText.getText(), TextView.BufferType.SPANNABLE);
}
See this Q&A for why the complicated pre API 21 version is needed to undo setTextIsSelectable(true):
请参阅此问答，了解为什么需要复杂的 pre API 21 版本来撤消setTextIsSelectable(true)：
This answer needs to be more thoroughly tested.
这个答案需要更彻底的测试。
I have tested the setShowSoftInputOnFocuson higher API devices, but after @androiddeveloper's comment below, I see that this needs to be more thoroughly tested.
我已经setShowSoftInputOnFocus在更高的 API 设备上进行了测试，但是在下面@androiddeveloper 的评论之后，我发现这需要进行更彻底的测试。
Here is some cut-and-paste code to help test this answer. If you can confirm that it does or doesn't work for API 11 to 20, please leave a comment. I don't have any API 11-20 devices and my emulator is having problems.
这里有一些剪切和粘贴代码来帮助测试这个答案。如果您可以确认它对 API 11 到 20 是否有效，请发表评论。我没有任何 API 11-20 设备，而且我的模拟器有问题。

Gathering solutions from multiple places here on StackOverflow, I think the next one sums it up:
在 StackOverflow 上从多个地方收集解决方案，我想下一个总结一下：
If you don't need the keyboard to be shown anywhere on your activity, you can simply use the next flags which are used for dialogs (got from here) :
如果您不需要在活动的任何位置显示键盘，您只需使用用于对话框的下一个标志（从这里获得）：
getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM, WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
If you don't want it only for a specific EditText, you can use this (got from here) :
如果您不希望它仅用于特定的 EditText，您可以使用它（从这里获得）：
public static boolean disableKeyboardForEditText(@NonNull EditText editText) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
editText.setShowSoftInputOnFocus(false);
return true;
}
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1)
try {
final Method method = EditText.class.getMethod("setShowSoftInputOnFocus", new Class[]{boolean.class});
method.setAccessible(true);
method.invoke(editText, false);
return true;
} catch (Exception ignored) {
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2)
try {
Method method = TextView.class.getMethod("setSoftInputShownOnFocus", boolean.class);
method.setAccessible(true);
method.invoke(editText, false);
return true;
} catch (Exception ignored) {
}
return false;
}
Or this (taken from here) :
或者这个（取自这里）：
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
editText.setShowSoftInputOnFocus(false);
else
editText.setTextIsSelectable(true);

I found this solution which works for me. It also places the cursor, when clicked on EditText at the correct position.
我找到了这个对我有用的解决方案。当单击 EditText 时，它还会将光标放置在正确的位置。
EditText editText = (EditText)findViewById(R.id.edit_mine);
// set OnTouchListener to consume the touch event
editText.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
v.onTouchEvent(event); // handle the event first
InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.hideSoftInputFromWindow(v.getWindowToken(), 0); // hide the soft keyboard
}
return true;
}
});

your_edit_text = (EditText) findViewById(R.id.editText_1);
