我用Zxing条形码创建了一个项目
我正在使用:
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);
}
}
运行应用程序后,我从条形码中获取数据然后再获取数据 显示"不幸停止"
