如何在Android中以编程方式更改Edittext光标颜色?

在android中,我们可以通过以下方式更改光标颜色:

android:textCursorDrawable="@drawable/black_color_cursor"

我们如何动态地做到这一点?

在我的情况下,我将可绘制的光标设置为白色,但是我需要将其更改为黑色。怎么办?

    // Set an EditText view to get user input

final EditText input = new EditText(nyactivity);

input.setTextColor(getResources().getColor(R.color.black));

回答:

使用一些反射对我有用

Java:

// https://github.com/android/platform_frameworks_base/blob/kitkat-release/core/java/android/widget/TextView.java#L562-564

Field f = TextView.class.getDeclaredField("mCursorDrawableRes");

f.setAccessible(true);

f.set(yourEditText, R.drawable.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="#ff000000" />

<size android:width="1dp" />

</shape>


您可以使用不需要XML的方法:

public static void setCursorColor(EditText view, @ColorInt int color) {

try {

// Get the cursor resource id

Field field = TextView.class.getDeclaredField("mCursorDrawableRes");

field.setAccessible(true);

int drawableResId = field.getInt(view);

// Get the editor

field = TextView.class.getDeclaredField("mEditor");

field.setAccessible(true);

Object editor = field.get(view);

// Get the drawable and set a color filter

Drawable drawable = ContextCompat.getDrawable(view.getContext(), drawableResId);

drawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);

Drawable[] drawables = {drawable, drawable};

// Set the drawables

field = editor.getClass().getDeclaredField("mCursorDrawable");

field.setAccessible(true);

field.set(editor, drawables);

} catch (Exception ignored) {

}

}
