科特林：

将光标设置到起始位置:

val editText = findViewById(R.id.edittext_id) as EditText
editText.setSelection(0)

将光标设置到EditText的末尾:

val editText = findViewById(R.id.edittext_id) as EditText
editText.setSelection(editText.text.length)

下面的Code是将光标放在第二个字符之后:

val editText = findViewById(R.id.edittext_id) as EditText
editText.setSelection(2)

JAVA:

将光标设置到起始位置:

 EditText editText = (EditText)findViewById(R.id.edittext_id);
 editText.setSelection(0);

将光标设置到EditText的末尾:

EditText editText = (EditText)findViewById(R.id.edittext_id);
editText.setSelection(editText.getText().length());

下面的Code是将光标放在第二个字符之后:

EditText editText = (EditText)findViewById(R.id.edittext_id);
editText.setSelection(2);

/**
 * Set cursor to end of text in edittext when user clicks Next on Keyboard.
 */
View.OnFocusChangeListener onFocusChangeListener = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View view, boolean b) {
        if (b) {
            ((EditText) view).setSelection(((EditText) view).getText().length());
        }
    }
};

mEditFirstName.setOnFocusChangeListener(onFocusChangeListener); 
mEditLastName.setOnFocusChangeListener(onFocusChangeListener);

这对我很有用!

editText.setOnKeyListener(new View.OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        editText.setSelection(editText.getText().length());
        return false;
    }
});

您应该能够在EditText的方法setSelection()的帮助下实现这一点，请参阅这里

editText。这里的setSelection很神奇。基本上选择让你把光标放在任何你想要的位置。

EditText editText = findViewById(R.id.editText);
editText.setSelection(editText.getText().length());

这将光标放置到EditText的末尾。基本上，editText.getText().length()会给出文本长度。然后使用setSelection with length。

editText.setSelection(0);

它用于将光标设置在起始位置(0)。

这是

Editable etext = edittext.getText();
Selection.setSelection(etext,edittext.getText().toString().length());
