Android开发拍身份证带人像框和国徽框效果

拍身份证时往往要带上外框辅助用户拍照，这也是很常见的需求。

一、思路

自定义Camera和自定义拍照的界面，把外框画上去，做个遮罩

二、效果图：

public class SecondActivity extends AppCompatActivity {

    private ImageView iv_result;
    private Context mContext;
    private ActivityResultLauncher<Intent> launcher;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mContext = this;

        launcher = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(), result -> {
            if (result.getResultCode() == RESULT_OK && result.getData() != null) {
                String photoPath = result.getData().getStringExtra(CameraActivity.KEY_CONTENT_TYPE);
                Log.i("photoPath",photoPath);
                if (!TextUtils.isEmpty(photoPath)) {
                    Glide.with(mContext)
                            .load(photoPath)
                            .into(iv_result);

                }
            }
        });

        iv_result = findViewById(R.id.iv_result);

        findViewById(R.id.tv_photo).setOnClickListener(new View.OnClickListener() {
