小编Ama*_*iam的帖子

我在我的应用程序中使用Glide库内部自定义适配器视图.但我有错误:

"You must not call setTag() on a view Glide is targeting" 

这部分代码:

 @Override
    public View getView(int position, View view, ViewGroup container) {
        ViewHolder holder;
        if (view == null) {
            holder = new ViewHolder();
            view = holder.imageView = new ImageView(context);
            view.setTag(holder);
        } else {
            holder = (ViewHolder) view.getTag();
        }

        holder.imageView.setAdjustViewBounds(true);
        LinearLayout.LayoutParams vp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
        holder.imageView .setLayoutParams(vp);
        holder.imageView .setScaleType(ImageView.ScaleType.CENTER_CROP);

        String var_news_article_images = imageIdList.get(getPosition(position));

        Glide.with(context)
                .load(var_news_article_images)
                .placeholder(R.drawable.placeholder)
               .into(holder.imageView);

               return view;
    }

那怎么解决呢？

我得到一个java.lang.OutOfMemoryError:在Android 1.4上运行gradle时超出了GC开销限制 ...这些是我的依赖:

        transitive = true;
    }

怎么解决这个问题？

我只是想在底部检测滚动nestedscrollview android的位置,以及调用函数.我的代码是:

scroll.getViewTreeObserver()
      .addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
           @Override
           public void onScrollChanged() {
               int totalHeight = scroll.getChildAt(0).getHeight();
               int scrollY = scroll.getScrollY();
               Log.v("position", "totalHeight=" + totalHeight + "scrollY=" + scrollY);
               if (scrollY==totalHeight) {
                   getPlaylistFromServer("more");
               }
           }
      });

但总高度与MAX ScrollY不同.怎么解决？

我的代码有问题.我的代码在Android Studio中标记为错误代码,但成功构建了gradle并在设备上运行,如下所示:

当前配置:

1. 我当前的项目在依赖项中使用了很多库.但是如果带有小库的项目不会像这样标记错误.
2. Android Studio 1.5 RC1
3. compileSdkVersion'Google Inc.:Google API:23
4. buildToolsVersion '23 .0.2'
5. classpath'com.android.tools.build:grad:1.3.1'

我做过的活动但没有解决问题:

1. 总是清理>重建项目
2. invalidate caches/restart>打开Android studio>打开这个项目
3. 关闭android studio>重启电脑>再次打开android studio>打开这个项目
4. 更新Android版本和SDK版本5.卸载Android Studio>重新安装Android Studio>打开项目

编辑:似乎错误来自android支持的每个代码,如recyclerview,CardView,APpCompact

我正在实施GPS追踪器以获取经度和纬度来自http://www.androidhive.info/2012/07/android-gps-location-manager-tutorial/.

要获得经度和纬度值,我使用此代码:

    gps = new GPSTracker(context);

    latitude_user= gps.getLatitude();
    longitude_user  = gps.getLongitude();

有些设备总是返回0,0值,对于某些设备它运行良好 ...那么如何解决它？

这是GPS Tracker.class

package com.tracking.bus.maps;

import android.app.Service;
import android.content.Context;
import android.content.DialogInterface;

public class GPSTracker extends Service implements LocationListener {

    private final Context mContext;

    // flag for GPS status
    boolean isGPSEnabled = false;

    // flag for network status
    boolean isNetworkEnabled = false;

我在我的Activity中实现了Collapsing ToolBar Layout.我在此活动中也创建了RecyclerView.我有问题,当我如何PopUp菜单项RecyclerView,折叠工具栏总是崩溃.

这是我的XML:

那么如何解决呢？

我在样式自定义复选框菜单项ActionBar时遇到问题。我已经实现了，但是没有样式。

我想改变资源

如果复选框已选中

如果未选中复选框

这是我的菜单项Action Bar.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"

        android:title="@string/actionbar_alarm"
        app:actionViewClass="android.widget.CheckBox"
        app:showAsAction="ifRoom"/>

        <item
        android:id="@+id/actionbar_interval"
        android:title="@string/actionbar_interval"
        app:actionViewClass="android.widget.Spinner"
        app:showAsAction="ifRoom"/>

        <item
        android:id="@+id/actionbar_log_track"
        android:title="@string/actionbar_log_track"
        app:showAsAction="never"/>
</menu>

风格的动作栏

         <item android:state_checked="true" android:drawable="@drawable/alram_on" />
         <item android:state_checked="false" …

我的操作栏中有问题.我正在尝试在ActionBar中的菜单项上添加一个复选框,但它不起作用.它只显示复选框的标题.

这是我的menu.xml:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.tracking.bus.maps.SingleViewMapsActivity" >

        <item
        android:id="@+id/actionbar_alarm"
        android:title="@string/actionbar_alarm"
        app:actionViewClass="android.widget.checkbox"
        app:showAsAction="ifRoom"/>
</menu>

我想在Fragment Android中实现Action Mode Compact.但是我收到错误我的代码中的FragmentActivity类型未定义方法startSupportActionMode(ActionMode.Callback):

list.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
                @Override
                public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                    getActivity().startSupportActionMode(modeCallBack);

                    return true;
                }
        });

getActivity().startSupportActionMode(modeCallBack);如何解决它会得到错误？

我有升级gradle:

dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }

至 :

dependencies {
        classpath 'com.android.tools.build:gradle:1.4.0-beta3'
    }
