如何获得编辑文本Android上的当前光标？

Question

我希望在每次触摸屏幕后获得编辑文本上的光标位置，但是在每次触摸onTouchListener事件之后，它返回的光标位置是先前选择的。

例如，我在文本中选择了位置号59，但得到了结果位置号8。

• Position 8是我早些时候选择的

public class MainActivity extends AppCompatActivity implements View.OnTouchListener {

    EditText text;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        text = findViewById(R.id.text);

        text.setText("Java is a programming language and computing pla" +
                "tform first released by Sun Microsystems in 1995. There are" +
                "lots of applications and websites that will not work unless you have Java in" +
                "stalled, and more are created every day. Java is fast, secure, and reliable. " +
                "From laptops to datacenters, game consoles to scientific supercomputers, cell" +
                " phones to the Internet, Java is everywhere!\n");

        text.setOnTouchListener(this);
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        int start = text.getSelectionStart();
        int end = text.getSelectionEnd();

        text.append(String.format("\nCurrent selection start=%s    end=%s",start, end));

        return false;
    }
 }

结果：

您可以使用"OnClickListener“来获取光标位置。因为"onTouch“是在光标位置更改之前调用的。

text.setOnClickListener {
        val start = text.getSelectionStart()
        val end = text.getSelectionEnd()
        Log.e("Log", "====>" + start + "  " + end)
}
