如何在EditText android中获取光标位置（x，y）

Question

如何在Android的EditText中获取光标位置x，y？ （其中x是行＃，y是列＃）

Answer 1

int pos = editText.getSelectionStart();
Layout layout = editText.getLayout();
int line = layout.getLineForOffset(pos);
int baseline = layout.getLineBaseline(line);
int ascent = layout.getLineAscent(line);
float x = layout.getPrimaryHorizontal(pos);
float y = baseline + ascent;

然后你得到光标像素的x，y位置。

Answer 2

您可以像这样找到当前选择的行号和列：

// Get the current selection's line number
int line = edittext.getLayout().getLineForOffset(edittext.getSelectionStart());

// Find the index for the start of the selected line. Subtract that from the current selection's index
int column = edittext.getSelectionStart() - edittext.getLayout().getLineStart(line);
