public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


    }

    public void image(View v) {
        //启动拍照
        Intent intent = new Intent();
        intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
        //指定保存路径
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "haha.jpg")));
        startActivityForResult(intent, 10);
    }

    public void audio(View v) {
        //启动摄像
        Intent intent = new Intent();
        intent.setAction(MediaStore.ACTION_VIDEO_CAPTURE);
        //指定保存路径
        intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "haha.3gp")));

        // 0：低质量   1：高质量
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
        startActivityForResult(intent, 20);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 10) {
            Toast.makeText(this, "拍照成功", Toast.LENGTH_SHORT).show();
        }

        if (requestCode == 20) {
            Toast.makeText(this, "摄像成功", Toast.LENGTH_SHORT).show();
        }
