今天分享的是用系统自带的相机实现一键拍照功能。
public class MainActivity extends AppCompatActivity { private static final int TAKE_PHOTO = 100; private ImageView iv; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); iv = (ImageView) findViewById(R.id.iv); } public void btn(View view) { switch (view.getId()){ case R.id.button: //跳转到拍照的意图 Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //判断系统中是否有照相机 if (takePhotoIntent.resolveActivity(getPackageManager())!=null){ startActivityForResult(takePhotoIntent,TAKE_PHOTO); } break; } } /** * 处理数据 * @param requestCode * @param resultCode * @param data */ @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); //判断请求码和返回码 if (requestCode==TAKE_PHOTO&&resultCode==RESULT_OK){ Bitmap bitmap = data.getParcelableExtra("data"); iv.setImageBitmap(bitmap); } } }
