我试图在ImageView周围对齐TextView.我使用以下代码:

 private void createSpannableText(){
        TextView myTextView = (TextView) findViewById(R.id.textView);
        SpannableStringBuilder builder = new SpannableStringBuilder();
        builder.append(this.getText(R.string.loren__ipsum__max));
        int lengthOfPart1 = builder.length();
        builder.append(" ");
        builder.append(this.getText(R.string.lorem__ipsum));
        Drawable d = getResources().getDrawable(R.drawable.myImage);
        d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight()); // <---- Very important otherwise your image won't appear
        ImageSpan myImage = new ImageSpan(d);
        builder.setSpan(myImage, 0, lengthOfPart1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        myTextView.setText(builder);
    }

但无法得到确切的结果.我该怎么办？在这种情况下我需要使用SpannableStringBuilder还是有另一种方法.请帮忙.我使用这个帖子http://majaxandroidtips.blogspot.in/2009/06/how-to-have-few-layout-elements-wrap_17.html 来获得解决方案.

PS:我还希望ImageView周围有6dp的边距

我包括我的样式的xml布局:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="Theme.Styled" parent="Theme.Sherlock">
        <item name="actionBarStyle">@style/Widget.MyApp.ActionBar</item>
        <item name="android:actionBarStyle">@style/Widget.MyApp.ActionBar</item>

    </style>

    <style name="Widget.MyApp.ActionBar" parent="Widget.Sherlock.Light.ActionBar">
        <item name="titleTextStyle">@style/Widget.MyApp.TitleTextStyle</item>
        <item name="background">@color/red</item>
        <item name="android:background">@color/red</item>
        <item name="windowContentOverlay">@null</item>
        <item name="android:windowContentOverlay">@null</item>
    </style>

    <style name="Widget.MyApp.TitleTextStyle" parent="TextAppearance.Sherlock.Widget.ActionBar.Title">
        <item name="android:textColor">@color/white</item>
        <item name="android:textSize">21sp</item>
    </style>

</resources>

一些关于互联网的搜索建议使用windowContentOverlay设置为@null.但是当我在xml风格中使用它时,它不会改变任何东西.任何人都可以帮忙做什么？

可能重复:
Android RuntimeException:无法实例化服务

我正在使用IntentService下载我的数据.我的IntentService类定义如下:

public class DownloadService extends IntentService{
super("DownloadService");
@Override
    protected void onHandleIntent(Intent intent) {
        //download tasks...
    }
}

AndroidManifest.xml中:

<appilcation>
<service android:name="DownloadService"/>
..
..
..
</application>

LauncherActivity.java:

@Override
public void onCreate(Bundle savedInstanceState) {
        ..
        ..
        ..
    Intent dwnldService = new Intent(this, DownloadService.class);
    startService(dwnldService);
}

但我仍然收到此错误:

我正在使用TextSwitcher来淡入淡出 - 当我设置文本时淡出动画.但是在更改文本时,将内容包装的宽度存在一些问题.

以下是我的TextSwitched xml:

                            <TextView
                                android:layout_width="wrap_content"
                                android:layout_height="wrap_content"
                                android:ellipsize="end"
                                android:maxLines="1"
                                android:scrollHorizontally="true"
                                android:textAppearance="?android:attr/textAppearanceSmall"
                                android:textColor="@android:color/white" />

                            <TextView
                                android:layout_width="wrap_content"
                                android:layout_height="wrap_content"
                                android:ellipsize="end"
                                android:maxLines="1"
                                android:scrollHorizontally="true"
                                android:textAppearance="?android:attr/textAppearanceSmall"
                                android:textColor="@android:color/white" />
                        </TextSwitcher>

我有字符串列表,当我从长字(例如"Hello World")更改为"World"时,textwitcher不会将字符串"World"的宽度换行,而是保留"Hello World"字样的宽度.

简而言之,宽度对于最长字的最大宽度保持固定.

请建议!!!

我创建了一个Dynamic LinearLayout,我想将这些布局添加到ListView.代码如下:

DynamicLayout代码:

import android.content.Context;
import android.widget.LinearLayout;
import android.widget.TextView;

public class DynamicContentLayout extends LinearLayout{
    private Context context;
    private int linearLayoutMargin;

    public DynamicContentLayout(Context context) {
        super(context);
        this.context = context;
        linearLayoutMargin = (int) context.getResources().getDimension(R.dimen.xlarge_margin_padding_fixed);
        initViews();
    }

    private void initViews() {
        LinearLayout.LayoutParams layout_lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        layout_lp.setMargins(linearLayoutMargin, linearLayoutMargin, linearLayoutMargin, linearLayoutMargin);
        this.setLayoutParams(layout_lp);
        this.setOrientation(LinearLayout.VERTICAL);
        this.addView(headerTitle("My Text"));

    }

    private TextView headerTitle(String title) {
        TextView txtView = new TextView(context);
        txtView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
        txtView.setPadding(6, 6, 6, 6);
        txtView.setText(title);
        txtView.setBackgroundColor(context.getResources().getColor(R.color.red));
        txtView.setTextColor(context.getResources().getColor(R.color.white));
        return txtView;
    }

}

我正在使用Cordova-3.3.0,在尝试为Android创建项目时,我收到以下错误 -

错误:请安装Android目标19(Android最新SDK).

我安装了最新的Android以及Android 18和17.即使我使用Cordova-3.2.0,我也得到相同的结果

未找到Android目标18

请问任何人都可以提出可能存在的问题吗？

我想从这里的项目中获得一个自动完成的文本字段.

有人可以帮忙吗？

以下是一个简单的SQL查询:

SELECT * FROM *table_name*
GROUP BY *column_name*

在我的系统中,我有MySQL 5.5.它工作得非常好.而在我朋友的系统中,他有MySQL 5.7,并且他收到以下错误:

错误1055(42000):SELECT列表的表达式#1不在GROUP BY子句中,并且包含非聚合列'testdb.assetentry.entryId',它在功能上不依赖于GROUP BY子句中的列; 这与sql_mode = only_full_group_by不兼容

很明显,这种情况正在发生,因为版本不同.

但我想知道的是背后的原因.

任何人都可以解释一下.

我正在尝试配置Jenkins以构建maven Web应用程序,以构建战争并将其部署到远程服务器.我浏览了互联网,发现在Post build Action下有一个选项来部署war.但我找不到选项.以下是截图.任何人都可以告诉我是否有任何解决方法来构建和部署战争？
