嗨,我使用片段A和第二片段使用b.调用b和使用的asynctask 方法,但我第一次使用这是完美的工作,但第二次然后崩溃应用程序和我的错误登录下面:::我工作三星平板电脑完美工作但三星核心移动崩溃的应用程序.

我的班级用于:

public class TakeCameraFragment extends Fragment {
    Camera mCamera = null; …

好吧,所以这变得非常烦人,试图让我的项目在出口时工作/

Progaurd一直给我这个错误:

我正在编写一个使用AutoCompleteTextView的Android应用程序,就像API示例一样.问题是我的文本太长,需要在下拉列表时换行.我有一个自定义list_item.xml,但只显示一行文本.如果与微调器一起使用,list_item.xml布局将包装为2行,但不包含AutoCompleteTextView.

main.java

public class main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.autocomplete_country);
        ArrayAdapter<String> adapter  = new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES);
        textView.setAdapter(adapter);
    }  

        static final String[] COUNTRIES = new String[] {
            "This is the first line that is too long and it needs to wrap content",
          "Albania", "Algeria", "American Samoa", "Andorra",
          "This is a second line that also needs to wrap its content",
              "Bahrain", "Bangladesh", "Barbados", "Belarus", "Belgium"
        };
}

main.xml中

<?xml version="1.0" …

我正在运行Android Studio 2.1.1并在两个设备上调试我的应用程序(我的x86_64 windows 10上有一个模拟器,另一个是我的HTC One M8).在调试过程中,如果我跳过代码,当它存在当前的方法或范围时,程序就会崩溃,在logcat中没有任何指示(我知道这是因为我故意添加了一个log.d作为最后一行,而最后一行我得到的消息是崩溃前来自此log.d的内容).

但是,如果我使用continue而不是跳过,应用程序只会退出当前函数,而不会崩溃应用程序.

我不知道这里发生了什么,它大大减慢了我的开发和调试速度.任何想法和建议将不胜感激.如果您需要更多信息,请告知我们,提前谢谢.

我需要为TextView设置初始透明度,但我不知道该怎么做.在iPhone上,可以使用alpha属性轻松完成.我尝试使用AlphaAnimation设置alpha但没有好处它不起作用.它结束时只返回100%alpha.

AlphaAnimation anim = new AlphaAnimation(1, 0.2f);
anim.setDuration(5000);
textView.startAnimation(anim);

有什么想法吗？

使用操作栏搜索界面时,窗口小部件将以纵向模式展开以占据屏幕的整个宽度,但在横向模式下会停止缩短.

有没有办法在SearchView上设置扩展布局参数,以便在用户键入搜索时完全填充操作栏？

见图:http: //i.imgur.com/3z8ZbJA.png

注意:我目前没有使用ActionBar Sherlock

编辑:这是我为了扩展全宽而做的.

searchView.setOnSearchClickListener(new OnClickListener() {
    private boolean extended = false;

    @Override
    public void onClick(View v) {
        if (!extended) {
            extended = true;
            LayoutParams lp = v.getLayoutParams();
            lp.width = LayoutParams.MATCH_PARENT;
        }
    }

});

我已在我的应用中实施了GCM(Google Cloud Messaging).Google Play服务库已自动生成values.xml,其中我senderId是:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="gcm_defaultSenderId">123</string>
</resources>

问题是我有其他语言环境,App Release期间的Lint给了我一个错误: Error:(3) Error: "gcm_defaultSenderId" is not translated in "fr" (French) [MissingTranslation]

因为它是自动生成的我无法设置translable = false.我应该怎么解决这个问题？

我有一个RecyclerView，其中每个列表行项目都有一个CheckBox. 在单独的列表行的布局预览中，Checkbox 显示正确，没有文本：

但是，当我查看布局预览作为RecyclerView（使用tools:listitem = "@layout/application_list_content"）的一部分时，我看到不需要的示例文本，如“项目 0”、“项目 1”、“项目 3”等：

问题：有没有办法让 Android Studio 的布局预览不显示示例文本 - “Item X” - 而只是显示一个空字符串？

的代码RecyclerView是：

<android.support.v7.widget.RecyclerView
    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:id="@+id/application_list"
    android:name="com.laurivan.android.ApplicationListFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginEnd="?listPreferredItemPaddingRight"
    android:layout_marginStart="?listPreferredItemPaddingLeft"
    app:layoutManager="LinearLayoutManager"
    tools:context="com.laurivan.android.ApplicationListActivity"
    tools:listitem="@layout/application_list_content"/>

项目行有这样的内容：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:tools="http://schemas.android.com/tools"
                android:layout_width="wrap_content"
                android:layout_height="@dimen/list_item_height_normal"
                android:orientation="horizontal"
    >

    <CheckBox
        android:id="@+id/app_checkBox"
        style="?android:attr/starStyle"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_alignParentEnd="true"
        android:layout_margin="0dp"
        android:checked="false"
        android:padding="0dp"
        tools:text=""
        />

</RelativeLayout>
