拍照后如何驗證不同的按鈕？

我有 2 個帶有特定影像的影像視圖，它發送到設備的相機，我想驗證，我希望在拍攝照片時它會根據拍攝照片的按鈕更改影像。

我試圖這樣做，但沒有奏效。

ImageView imageV, imageV2;
static final int IMAGE_REQUEST = 1;
private static final int PERMISSION_REQUEST = 2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

imageV = findViewById(R.id.image_view);
imageV2 = findViewById(R.id.image_view_2);

btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
       Intent camara = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
       if (camara.resolveActivity(getPackageManager()) != null) {
          startActivityForResult(camara, IMAGE_REQUEST);
       }
    }
});

btnIne.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
       Intent camara = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
       if (camara.resolveActivity(getPackageManager()) != null) {
          startActivityForResult(camara, IMAGE_REQUEST);
       }
    }
 });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == IMAGE_REQUEST) {
        if (resultCode == Activity.RESULT_OK) {
            //Images to change
            imageV.setImageResource(R.drawable.image_view_2do);
            imageV2.setImageResource(R.drawable.image_view2_2do);

        }
        else {
            //Default images
            imageV.setImageResource(R.drawable.image_view_1er);
            imageV2.setImageResource(getResources().getString(R.string.image_view2_1er));
        }
    }

}
  

uj5u.com熱心網友回復：

您必須在 startActivityForResult 中添加不同的請求代碼。就像您對兩個按鈕都使用了 IMAGE_REQUEST 一樣。

例如：

ImageView imageV, imageV2;
static final int IMAGE_REQUEST = 1;
static final int IMAGE_REQUEST_2 = 2;
private static final int PERMISSION_REQUEST = 2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

imageV = findViewById(R.id.image_view);
imageV2 = findViewById(R.id.image_view_2);

btnStatementAccount.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
       Intent camara = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
       if (camara.resolveActivity(getPackageManager()) != null) {
          startActivityForResult(camara, IMAGE_REQUEST);
       }
    }
});

btnIne.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
       Intent camara = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
       if (camara.resolveActivity(getPackageManager()) != null) {
          startActivityForResult(camara, IMAGE_REQUEST_2);
       }
    }
 });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == IMAGE_REQUEST) {
        if (resultCode == Activity.RESULT_OK) {
            //Images to change
            imageV.setImageResource(R.drawable.image_view_2do);
            imageV2.setImageResource(R.drawable.image_view2_2do);

        }
        else if (requestCode == IMAGE_REQUEST_2) {
        if (resultCode == Activity.RESULT_OK) {
            //Images to change
            imageV.setImageResource(R.drawable.image_view_2do);
            imageV2.setImageResource(R.drawable.image_view2_2do);

        }
        else {
            //Default images
            imageV.setImageResource(R.drawable.image_view_1er);
            imageV2.setImageResource(getResources().getString(R.string.image_view2_1er));
        }
    }

}
