我在Eclipse中创建了一个简单的"Hello World"程序.我什么都不添加到Java文件,只在文件中添加一个文本视图main.xml作为

//main.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Hello World"
    />
</LinearLayout>

现在,当我运行我的程序时,它会在控制台中显示以下内容.

//console output

我有设置标签作为UPDATE 29/05/2015 这篇文章.标签在我的Nexus 4手机上占据全宽,但在nexus 7平板电脑上占据中心位置而不是覆盖全屏宽度.

我正在研究社交移动应用.它可以选择录制个人资料视频.我的刻录机的问题是它反映了实际的视频.我知道这是默认行为,但希望它像sanpchat一样工作.

预习

录制和播放后

这是我的代码

// return camera instance when activity open first time
private Camera getCameraInstance() {
    // TODO Auto-generated method stub
    releaseCamera();
    releaseMediaRecorder();
    Camera c = null;
    try {
        cameraId = findFrontFacingCamera();
        if (cameraId < 0) {
            cameraId = findBackFacingCamera();
        }
        c = Camera.open(cameraId);

        // setCameraDisplayOrientation(this,cameraId,c);
        //setCameraDisplayOrientation(this, cameraId, c);
        c.setDisplayOrientation(90);
    } catch (Exception e) {
        // Camera is not available (in use or does not exist)
    }
    return c; // returns null if camera is unavailable
}
// return …

我正在绘制一个绘图应用程序,我想用手指触摸移动屏幕绘制心形.所以我将BitmapShader设置为如下代码

//Initialize the bitmap object by loading an image from the resources folder
Bitmap fillBMP = BitmapFactory.decodeResource(context.getResources(), R.drawable.heart);
fillBMP = Bitmap.createScaledBitmap(fillBMP, 20, 20, false);                
//Initialize the BitmapShader with the Bitmap object and set the texture tile mode
shader= new BitmapShader(fillBMP, Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);

然后我分配着色器绘画对象.

paint.setShader(preset.shader);

我还设置了触摸监听器来跟踪用户手指.在用户触摸时,我在canvas对象上绘制为.

Path path = new Path();
path.moveTo(mid1.x, mid1.y);
path.quadTo(midmid.x, midmid.y, mid2.x, mid2.y);
canvas.drawPath(path, paint);

这给了我这个

有些心形被歪曲,而且这些都是重复的.我想要的不是这些重复而且永远不会像这样发作.

提前致谢.

我通过点击部署选项在Google compute Engine中设置了Redis群集.现在我想从我的节点js代码连接到这个redis服务器使用'ioredis'这里是我的代码连接到redis的单个实例

var Redis = require("ioredis");

var store = new Redis(6379, 'redis-ob0g');//to store the keys
var pub =   new Redis(6379, 'redis-ob0g');//to publish a message to all workers
var sub =   new Redis(6379, 'redis-ob0g');//to subscribe a message 

var onError = function (err) {
    console.log('fail to connect to redis ',err);
};
store.on('error',onError);
pub.on('error',onError);
sub.on('error',onError);

它奏效了.现在我想连接到redis作为集群,所以我将代码更改为

/**
 * list of server in replica set
 * @type {{port: number, host: string}[]}
 */
var nodes =[
    {   port: port,    host: …
