參考 Android拍照、錄影、錄音代碼範例

 

public class MyCameraActivity extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        Button btnCamera = (Button) findViewById(R.id.btnCamera);        btnCamera.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                // TODO Auto-generated method stub                letCamera();            }        });    }    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);        switch (requestCode) {        case 1:// 拍照            if (resultCode == RESULT_OK) {                Toast.makeText(this, "拍攝成功", Toast.LENGTH_SHORT).show();            }            break;        default:            break;        }    }    protected void letCamera() {        // TODO Auto-generated method stub        Intent imageCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);        String strImgPath = Environment.getExternalStorageDirectory()                .toString() + "/dlion/";// 存放照片的檔案夾        String fileName = new SimpleDateFormat("yyyyMMddHHmmss")                .format(new Date()) + ".jpg";// 照片命名        File out = new File(strImgPath);        if (!out.exists()) {            out.mkdirs();        }        out = new File(strImgPath, fileName);        strImgPath = strImgPath + fileName;// 該照片的絕對路徑        Uri uri = Uri.fromFile(out);        imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);        imageCaptureIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);        startActivityForResult(imageCaptureIntent, 1);    }}
