android EditText获取光标位置并插入删除字符与设置光标颜色

1.获取光标位置

 

[java] int index = editText.getSelectionStart();   int index = editText.getSelectionStart();

2.在光标处插入字符

 

[java] int index = editText.getSelectionStart();  Editable editable = editText.getText();  editable.insert(index, "aaaa");  

3.删除光标前字符

 [java] int index = editText.getSelectionStart();  Editable editable = editText.getText();  editable.delete(index-1, index);   int index = editText.getSelectionStart();Editable editable = editText.getText();editable.delete(index-1, index); 

修改Android EditText光标颜色

EditText有一个属性：android:textCursorDrawable，这个属性是用来控制光标颜色的

android:textCursorDrawable="@null"，"@null"作用是让光标颜色和textcolor一样
