I am trying to implement Camera application in android,and i got some code from net to create a Live Camera through WebCam.Upto this no problem.Now i have to capture the images when click the button, and i displayed the captured images in the Dialog window.Without any exception the program is running but the captured image is not displayed,some default image is displayed.

我的code是

public void captureImage()
{
	Camera.Parameters params = camera.getParameters();
	camera.setParameters(params);
	Camera.PictureCallback jpgCallback = new PictureCallback() 
	{
		public void onPictureTaken(byte[] data, Camera camera) 
		{
			try
			{
				Dialog d=new Dialog(c);
		    	d.setContentView(0x7f030000);
				BitmapFactory.Options opts = new BitmapFactory.Options();
    			Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length,opts);
    			TextView tv=(TextView)d.findViewById(0x7f050001);
    			ImageView i=(ImageView)d.findViewById(0x7f050000);
    	    	i.setImageBitmap(bitmap);
    			tv.setText("Hai"+data.length);
    			d.show();
			}
			catch(Exception e)
			{
				AlertDialog.Builder alert=new AlertDialog.Builder(c);
				alert.setMessage("Exception1"+e.getMessage());
				alert.create();
				alert.show();
			}

推荐答案

如果这是在模拟器上，唯一可用的摄像机图像是默认的图像。

If this is on the emulator, the only available camera image is a default image.

在一个完全无关的音符，不要引用由原始数据资源（例如， d.setContentView（0x7f030000））。使用生成的研究类（例如， R.layout.something ）。这些数字的将会的变化，而当他们改变你的应用程序的将会的突破。

On a completely unrelated note, DO NOT reference resources by raw numbers (e.g., d.setContentView(0x7f030000)). Use the generated R class (e.g., R.layout.something). Those numbers will change, and when they change your application will break.
