Android相机预览教程

我对我遵循的教程有一个小问题。我想制作一个带有相机预览的 Android 应用程序，但到目前为止我还没有找到任何好的教程来展示如何做到这一点。链接在这里教程 http://www.java2s.com/Code/Android/Hardware/CameraWithIntent.htm我不太确定是否可以使用“有意向的相机”而不是“相机预览”？我该怎么办。

谢谢 ：）

下面的教程将为您提供帮助。

调用内置相机意图拍照。

public class demo extends Activity {

Button ButtonClick;
int CAMERA_PIC_REQUEST = 1337; 


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

    ButtonClick =(Button) findViewById(R.id.Camera);
    ButtonClick.setOnClickListener(new OnClickListener (){
        @Override
        public void onClick(View view)
        {
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            // request code

            startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

        }
    });

}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    if( requestCode == 1337)
    {
    //  data.getExtras()
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");

          Now you have received the bitmap..you can pass that bitmap to other activity
          and play with it in this activity or pass this bitmap to other activity
          and then upload it to server.
    }
    else 
    {
        Toast.makeText(demo.this, "Picture NOt taken", Toast.LENGTH_LONG);
    }
    super.onActivityResult(requestCode, resultCode, data);
}
}
