Edittext cursor is invisible in android 4.0

问题:

I have an edit-text input in android 4.0 and the Cursor is not showing inside it.

What can make the cursor not appear in the input field?

回答1:

Make android:cursorVisible="true"

and

If you have used android:textColor then set the android:textCursorDrawable attribute to @null.

Happy coding ;)

I had a similar problem but it was because the cursor is actually white and I had a white background. I needed to be able to change the cursor to black in code somehow and used this approach.

I created a layout resource called textbox.axml which contained this

   <?xml version="1.0" encoding="utf-8"?>
   <EditText xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="This is a template"
    android:background="#ffffff"
    android:textColor="#000000"
    android:cursorVisible="true"
    android:textCursorDrawable="@null" />

I then applied this layout in code (C# because I am using Xamarin) thus

    EditText txtCompletionDate = (EditText)LayoutInflater.Inflate(Resource.Layout.textbox, null);

but it is similar in Java.

I happened quite same problem - cursor was showing up only after user types some characters. I tried solutions listed here, but without any success on my device. What actually work for me, is setting blank text to my edittext:

EditText editText = findViewById(R.id.edit_text);
editText.setText("");

This "fakes" the user input, and cursor appears.

My issue was that I was using the AppCompat theme, but I had some custom view classes that extended EditText that needed to extend AppCompatEditText in order for the AppCompat style to be applied correctly.

回答5:

Add this line for your edit text in the xml file.

android:textCursorDrawable="@null"

Add this line for your edit text in the xml file.

android:cursorVisible="true"

I found what was causing it to happen to me.

You need to inherit it from the application's theme. I'm not sure what the line item needs to be exactly, but android:Theme has it so inheriting that will do that trick.

Using the default AppBaseTheme will work (it has android:Theme.Light as it's parent).

To use AppBaseTheme put android:theme="@style/AppBaseTheme" into your application tag in the manifest. You can also use a custom style and multiple levels of inheritance so long as one of them has parent="android:Theme" in the style tag.Like I said it may be possible to have it without that, just using certain line item(s) but I don't know what those would be.

If you don't need a custom theme you can just use

android:theme="@android:style/Theme"

In My case the cursor is visible if user language is English but if he change his language to Arabic then its not visible.

To fix this I have created on custom drawable for cursor.

Cursur shap at drawable/black_cursor.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
    <solid android:color="#a8a8a8"/><!-- This is the exact color of android edit text Hint -->
    <size android:width="1dp" />
</shape>

Edit Text:

<EditText
    android:id="@+id/user_name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:textCursorDrawable="@drawable/black_cursor"
    />

Just adding my own personal fix to anyone it might help. I had tried everything here but forcing android:background="@null" was causing a very tiny cursor only at the end of my right aligned TextEdit (it was right working fine elsewhere).

Simply adding android:padding="1dp" in my TextEdit solved the issue.

As mentioned above, here's the actual line
android:textCursorDrawable="@null"

 <EditText
               android:textCursorDrawable="@null"
                android:imeOptions="actionNext"
                android:id="@+id/edSMobile"
                 android:layout_width="match_parent"
                android:layout_height="wrap_content"                    
                android:background="@drawable/edit_corner"                    
                android:inputType="phone" />
