推荐答案

以下code将复制文本到剪贴板剪贴板，然后获取文本和搜索吧..

The following code will copy your text to clipboard then from clipboard fetch the text and search it..

 private void emulateShiftHeld(WebView view)
 {
     try
     {
         KeyEvent shiftPressEvent = new KeyEvent(0, 0, KeyEvent.ACTION_DOWN,
                                                 KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0);
         shiftPressEvent.dispatch(view);

     }
     catch (Exception e)
     {
         Log.e("dd", "Exception in emulateShiftHeld()", e);
     }
 }

以下code将突出显示您所选择的文字...

The following code will highlight you the text you have selected...

ClipboardManager ClipMan = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
ClipMan.setText(ClipMan.getText().toString());
wb.findAll(ClipMan.getText().toString());
try
{
    Method m = WebView.class.getMethod("setFindIsUp", Boolean.TYPE);
    m.invoke(wb, true);
}
catch (Throwable ignored){}
