我在尝试生成已签名的APK时遇到此错误.问题是,我的应用程序能够在我的设备上正常运行和调试.我不知道为什么当我尝试生成APK时,出现了这个错误.如何忽略此错误并生成签名的APK？我正在使用Android Studio 1.2.1.1 for Mac.

我收到了这份崩溃报告:

ZhuangDictActivity中的第311行是searchProgressDialog.dismiss(),如下所示:

public void onPageFinished(WebView view, String url) {
                    searchProgressDialog.dismiss();
                    onConfigurationChanged(ZhuangDictActivity.this.getResources().getConfiguration());
                    super.onPageFinished(view, url);
                }

这是ProgressDialog.show:

public void onPageStarted(WebView view, String url,
                        Bitmap favicon) {
                    searchProgressDialog.setMessage("Loading");
                    searchProgressDialog.show();
                    super.onPageStarted(view, url, favicon);
                }

在WebView完成加载之前更改方向时发生崩溃.

我想修改的开源字典项目,其使用ActionBarSherlock SearchView$SearchAutoComplete.例如,我有一个名为"Google Play"的条目.该SearchView能够当我输入"谷歌",返回的建议,但如果我搜索"播放"事实并非如此.如何启用SearchView能够搜索包含文本的条目？

        public boolean onQueryTextChange(String newText) {
            if (MdxDictBase.isMdxCmd(newText)){
                currentEntry.setEntryNo(DictEntry.kSystemCmdEntryNo);
            }
            if (!skipUpdateEntryList) {
                dict.locateFirst(newText, true, true, true, false, currentEntry);
                syncHeadwordList();
            }
            skipUpdateEntryList = false;
            return true; //return false if want the system provide a suggestion list?
        }

完整的代码可以在这里找到.

这是Cursor我从这里找到的查询.

public Cursor query(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) {
        Log.d(TAG, "Got query:" + uri.toString());
        if (uri.getPath() != null && uri.getPath().startsWith(SEARCH_PATH)) { …

我在Google Play控制台收到了此崩溃报告,这是我自己从未体验过的.

我使用这种showDropDown方法从屏幕底部留下50 dp的空间,这样下拉菜单就不会覆盖我底部的Admob广告.

public void showDropDown() {
    Rect displayFrame = new Rect();
    getWindowVisibleDisplayFrame(displayFrame);

    int[] locationOnScreen = new int[2];
    getLocationOnScreen(locationOnScreen);

    int bottom = locationOnScreen[1] + getHeight();
    int availableHeightBelow = displayFrame.bottom - bottom;
    Resources r = getResources();
    int bannerHeight = Math.round(TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 50, …

A 有一个DropdownButtonFormField显示长文本的项目之一。长文本能够在下拉菜单中以多行显示。

然而选择后，只显示 1 行文本。第二行变得隐藏。

String _selectedState = '';
List<String> _stateList = ['a very very long long long long long text'];

                DropdownButtonFormField<String>(
                  isExpanded: true,
                  value: _selectedState,
                  onChanged: (state) {
                   
                  },                     
                  items: _stateList
                      .map<DropdownMenuItem<String>>((String value) {
                    return DropdownMenuItem<String>(
                      value: value,
                      child: Text(value),
                    );
                  }).toList(),
                ),

怎么解决这个问题呢？

我使用它在UITableView的页脚上显示Admob广告:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
    GADBannerView *sampleView = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner];

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    {
        sampleView.hidden=true;
    }

    sampleView.adUnitID = @"myID";

    sampleView.rootViewController = self;

    [sampleView loadRequest:[GADRequest request]];
    return sampleView;
}
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
    return 50.0;
}

我没有真正的iPhone设备,所以我只在模拟器上测试它.如果软件键盘被隐藏并且我使用MacBook键盘输入了单词,则上面的代码可以正常工作.但是,当我在模拟器中打开软件键盘时,广告无法在页脚加载.相反,它会加载到搜索栏下方.我该怎么解决这个问题？我不知道这个错误是否也发生在真实设备中.

我在我的 Google Play Console 中收到了这个崩溃报告，我自己从未经历过，也无法重现。

崩溃报告没有提到导致崩溃的类。我最好的猜测是遵循自定义TextView。

private void customTextView(TextView view) {
        SpannableStringBuilder spanTxt = new SpannableStringBuilder(
                Html.fromHtml(definition[0])); …

我有一个按照本教程创建的材料设计导航抽屉.

按下后退按钮时,应用程序退出.我想要做的是关闭背面的导航抽屉.这是原始代码:

drawerFragment = (FragmentDrawer)
                getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
        drawerFragment.setUp(R.id.fragment_navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout), mToolbar);
        drawerFragment.setDrawerListener(this);

我补充说:

public void onBackPressed() {
        if (this.drawerFragment.isDrawerOpen(GravityCompat.START)) {
            this.drawerFragment.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }

但是,我得到错误无法解决方法isDrawerOpen和closeDrawer.

我怎样才能让它发挥作用？

我使用此代码将横幅广告放在左下方.

CGPoint origin = CGPointMake(0.0,
                             self.view.frame.size.height -
                             CGSizeFromGADAdSize(kGADAdSizeBanner).height);
bannerView_ = [[GADBannerView alloc] initWithAdSize:kGADAdSizeBanner
                                             origin:origin];

如何将横幅定位在底部中心？

这是我的WebActivity.class.我知道要加载特定的URL,我们必须使用:

webView.loadUrl("file:///android_asset/about.html");

WebActivity.class从另一个活动中调用Intent.

Intent intent = new Intent(this, WebActivity.class);
            startActivity(intent);

我想要做的是,是否有可能做出类似的事情:

webView.loadUrl(url);

然后在我的另一个活动中,我将URL放在intent中,以便加载URL WebActivity.class？

Intent intent = new Intent(this, WebActivity.class);
url="file:///android_asset/about.html";
            startActivity(intent);
