如何在安卓系统中的EditText中移动光标

EditText editText = findViewById(R.id.editText);
editText.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        int clickPosition = editText.getSelectionStart(); // 获取点击的位置
        // 根据点击的位置计算出新的光标位置
        int newPosition = calculateNewCursorPosition(clickPosition);
        editText.setSelection(newPosition); // 移动光标到新的位置
    }
});

EditText editText = findViewById(R.id.editText);
editText.setOnKeyListener(new View.OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (event.getAction() == KeyEvent.ACTION_DOWN) {
            if (keyCode == KeyEvent.KEYCODE_DPAD_UP) {
                // 向上移动光标的逻辑
                int currentPosition = editText.getSelectionStart();
                int newPosition = calculateNewCursorPositionUp(currentPosition);
                editText.setSelection(newPosition);
                return true;
            } else if (keyCode == KeyEvent.KEYCODE_DPAD_DOWN) {
                // 向下移动光标的逻辑
                int currentPosition = editText.getSelectionStart();
                int newPosition = calculateNewCursorPositionDown(currentPosition);
                editText.setSelection(newPosition);
                return true;
            } else if (keyCode == KeyEvent.KEYCODE_DPAD_LEFT) {
                // 向左移动光标的逻辑
                int currentPosition = editText.getSelectionStart();
                int newPosition = calculateNewCursorPositionLeft(currentPosition);
                editText.setSelection(newPosition);
                return true;
            } else if (keyCode == KeyEvent.KEYCODE_DPAD_RIGHT) {
                // 向右移动光标的逻辑
                int currentPosition = editText.getSelectionStart();
                int newPosition = calculateNewCursorPositionRight(currentPosition);
                editText.setSelection(newPosition);
                return true;
            }
        }
        return false;
    }
});
