如果我添加一个EditText
XML,我可以设置textCursorDrawable="@null"
:
<EditText
android:id="@+id/txtE3Casecode4"
android:layout_width="30dp"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#C7C7C5"
android:textCursorDrawable="@null"
android:ems="10"
android:inputType="number"

现在我画一个EditText
Java.我想要设定android:textCursorDrawable="@null"
.
LinearLayout.LayoutParams paramtext = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.FILL_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
EditText txtOther = new EditText(this);
txtOther.setLayoutParams(paramtext);
txtOther.setBackgroundColor(Color.WHITE);
txtOther.setTextColor(Color.BLACK);
txtOther.setId(99999);
// txtOther.setCursorDrawable ?

怎么设置它?

没有公共API来设置光标可绘制.您可以使用反射以编程方式设置它.该字段mCursorDrawableRes
未更改,因此这应该适用于所有设备,除非制造商更改了某些内容或稍后进行了更改.
EditText yourEditText = new EditText(context);
...
try {
// 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);
} catch (Exception ignored) {
}

在您的应用中定义可绘制的光标:
<?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>

您还可以使用以下方法设置光标颜色:
public static void setCursorDrawableColor(EditText editText, int color) {
try {
Field fCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
fCursorDrawableRes.setAccessible(true);
int mCursorDrawableRes = fCursorDrawableRes.getInt(editText);
Field fEditor = TextView.class.getDeclaredField("mEditor");
fEditor.setAccessible(true);
Object editor = fEditor.get(editText);
Class<?> clazz = editor.getClass();
Field fCursorDrawable = clazz.getDeclaredField("mCursorDrawable");
fCursorDrawable.setAccessible(true);
Drawable[] drawables = new Drawable[2];
drawables[0] = editText.getContext().getResources().getDrawable(mCursorDrawableRes);
drawables[1] = editText.getContext().getResources().getDrawable(mCursorDrawableRes);
drawables[0].setColorFilter(color, PorterDuff.Mode.SRC_IN);
drawables[1].setColorFilter(color, PorterDuff.Mode.SRC_IN);
fCursorDrawable.set(editor, drawables);
} catch (Throwable ignored) {
}
}
