我想提醒人们,如果一个页面没有加载,并且吐司功能不能保持足够长的时间(但我留下的代码和评论如果我想回去的话)。所以我现在试图做一个自定义对话框,但不会弹出。自定义对话框来提醒网页没有加载
我基本上打开网页,其中工程 我在状态栏中加入了装载机所以人们会看到页面加载,而工作 我添加代码,以保持导航的应用程序,所以人不出口到一个新的浏览器,而工作 正如我所说的,面包技术上的工作,但不熬夜,只要我想 然后我添加的自定义警告对话框,而这也正是我失败
我还为自定义提醒创建了一个单独的XML文件
然后我甚至还没有得到这一点,但我是否需要添加co de关闭它,或者只是点击后退按钮自动关闭它?
谢谢!
这里是我的java文件
public class FC extends Activity {
WebView mWebView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//this one line added for progress support
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.web);
//makes progress bar visible
getWindow().setFeatureInt(Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);
//get web view
mWebView = (WebView) findViewById(R.id.webWeb);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setSupportZoom(true);
mWebView.getSettings().setBuiltInZoomControls(true);
mWebView.setInitialScale(45);
mWebView.loadUrl("http://www.chipmunkmobile.com");
//sets the Chrome client
final Activity MyActivity = this;
mWebView.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view, int progress)
{
//makes the bar disappear after URL is loaded, and changes string to Loading...
MyActivity.setTitle("Loading...");
MyActivity.setProgress(progress * 100);
//return the app name after finish loading
if(progress == 100)
MyActivity.setTitle(R.string.app_name);
}
});
//makes page stay in same web client
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
//looks to see if connects
mWebView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
//Toast.makeText(getApplicationContext(), "NO CONNECTION?\nVisit the Cyberspots in the SW and NW Halls to find out how to get on the free WiFi",
//Toast.LENGTH_LONG).show();
//showDialog(0);
AlertDialog.Builder builder;
AlertDialog alertDialog;
Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.custom_dialog,
(ViewGroup) findViewById(R.id.layout_root));
TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("WHATEVER");
ImageView image = (ImageView) layout.findViewById(R.id.imgid);
image.setImageResource(R.drawable.img);
builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();
}
});
}
代码下面是我在.xml文件
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/layout_root"
android:padding="10dp">
<ImageView android:id="@+id/imgid"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="10dp"
/>
<TextView android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textColor="#FFF"

</LinearLayout>
感谢您尝试,但崩溃的程序。任何其他建议? – SnowboardBruin
它是如何使程序崩溃的?你可以发布堆栈跟踪吗? –
