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)。

editText.accessibilityDelegate = object : View.AccessibilityDelegate() {
    override fun sendAccessibilityEvent(host: View?, eventType: Int) {
        super.sendAccessibilityEvent(host, eventType)
        if (eventType == TYPE_VIEW_TEXT_SELECTION_CHANGED) {
            editText.setSelection(editText.length())
        }
    }
}

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

如果你的EditText不清楚:

editText.setText("");
editText.append("New text");

or

editText.setText(null);
editText.append("New text");

这是

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

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);
