Answer 1

来自扩展 WebView 的类：

public void selectAndCopyText() {
try {
    Method m = WebView.class.getMethod("emulateShiftHeld", null);
    m.invoke(this, null);
} catch (Exception e) {
    e.printStackTrace();
    // fallback
    KeyEvent shiftPressEvent = new KeyEvent(0,0,
         KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_SHIFT_LEFT,0,0);
    shiftPressEvent.dispatch(this);
}

}

然后你必须使用 ClipboardManager 来观察新文本。
