问题描述
在我的Android应用程序中,我想要带android:editable="false"
的EditText
,但是光标闪烁.将可编辑"设置为false后,光标闪烁似乎不起作用.
In my Android application, I want an EditText
with android:editable="false"
but the cursor blinking. The cursor blinking seems doesn't work after "editable" is set to false.
我只想使用自己的键盘小部件(而不是系统的软键盘),并保持光标闪烁.
I just want to use my own Keyboard widget(not the system's soft keyboard), and keep the cursor blinking.
有什么想法可以实现这一目标吗?
Is there any idea to make that possible?
推荐答案
也许尝试完全忽略xml属性android:editable
,然后结合以下内容尝试使用
Maybe try leaving out the xml attribute android:editable
entirely and then try the following in combination to
保持光标闪烁,并且防止触摸事件弹出本机IME(键盘).
keep the cursor blinking and prevent touch events from popping up a native IME(keyboard)..
/*customized edittext class
* for being typed in by private-to-your-app custom keyboard.
* borrowed from poster at http://stackoverflow.com/questions/4131448/android-how-to-turn-off-ime-for-an-edittext
*/
public class EditTextEx extends EditText {
public EditTextEx(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public boolean onCheckIsTextEditor() {
return false; //for some reason False leads to cursor never blinking or being visible even if setCursorVisible(true) was called in code.
}
}
第2步将上述方法更改为return true;
Step 2change the above method to say return true;
第3步在上面的类中添加另一个方法.
Step 3Add another method to above class.
@Override
public boolean isTextSelectable(){
return true;
}
第4步在已实例化此类实例并称为viewB
的其他位置,我添加了一个新的触摸事件处理程序
Step 4In the other location where the instance of this class has been instantiated and called viewB
I added a new touch event handler
viewB.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent event) {
viewB.setCursorVisible(true);
return false;
}
});
步骤5检查并确保XML和或EditText实例化代码将IME/键盘类型声明为"none".我没有确认相关性,但是我也使用下面的可聚焦属性.
Step 5 Check to make sure XML and or EditText instantiation code declares IME/keyboard type to be 'none'. I didnt confirm relevance, but Im also using the focusable attributes below.
<questionably.maybe.too.longofa.packagename.EditTextEx
android:id="@+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:focusable="true"
android:focusableInTouchMode="true"
android:inputType="none">
很抱歉有这么多xml属性.我的代码全部使用了它们,并在4.2.1
中进行了测试,并产生了结果.
Sorry for so many xml attributes. My code uses them all, testing in 4.2.1
, and has results.
希望这会有所帮助.
