[英]Error with onRequestPermission / onActivityResult Android Studio
[英]Android Studio startActivity inside onActivityResult
我用Zxing條碼創建了一個項目
我在用 :
onActivityResult() :
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Intent toStart = null;
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Procces..: " + result.getContents(), Toast.LENGTH_LONG).show();
toStart=new Intent(this,BrowserKotaLama.class);
// result.getContets() --> is link URL
// Here i want to open new activity with Webview
// and Webview open that url
//
}
} else {
// This is important, otherwise the result will not be passed to the fragment
super.onActivityResult(requestCode, resultCode, data);
}
if (toStart!=null){
startActivity(toStart);
}
}
運行該應用程序后,我從條形碼中獲取數據,然后顯示“不幸停止”
