【问题描述】：

我在从图库中选择不同图像时尝试设置不同的名称，但只选择一个名称并在所有文本视图中设置..

public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_PICTURE) {
                selectedImageUri = data.getData();
                imageName = selectedImageUri.getPath();

                if (mbinding.includeMainUploadIdcard.filenamePancard.getText().toString().equals("")) {
                    mbinding.includeMainUploadIdcard.filenamePancard.setText(imageName);
                    mbinding.includeMainUploadIdcard.selectPancard.setVisibility(View.VISIBLE);
                }

                if (mbinding.includeMainUploadIdcard.filenameAdharcard.getText().toString().equals("")) {
                    mbinding.includeMainUploadIdcard.filenameAdharcard.setText(imageName);
                    mbinding.includeMainUploadIdcard.selectAdhar.setVisibility(View.VISIBLE);

                }

                if (mbinding.includeMainUploadIdcard.filenameElectricityBill.getText().toString().equals("")) {
                    mbinding.includeMainUploadIdcard.filenameElectricityBill.setText(imageName);
                    mbinding.includeMainUploadIdcard.selectBill.setVisibility(View.VISIBLE);

                }
}
}

想从选中的图片中获取图片名称？

标签： android image android-intent textview implicit

【解决方案1】：

当您选择单个图像时，您会通过 data.getData() 获取图像路径。而在多张图片的情况下，通过data.clipData获取所有图片路径。

您可以使用以下代码：

if (resultCode == RESULT_OK) {
        if (requestCode == SELECT_PICTURE) {

            // For multiple images
            if(data.clipData!=null)
            {
               for(int i=0;i<data.clipData.ietmCount;i++){
                   imageUri=data.clipData.getItemAt(i).uri
                   }
            
            }else {
            selectedImageUri = data.getData();
            imageName = selectedImageUri.getPath();
            }

            }
}

我用这个代码来显示图片，它的名字来自画廊：

主要活动

public class MainActivity extends AppCompatActivity {

ImageView imageView ;

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

    imageView = (ImageView) findViewById(R.id.imageView);
    
    /this code will let user to pick image from gallery
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    Intent.createChooser(intent,"title");
    startActivityForResult(intent,10);

}

// when we get back, the image we have selected will be here :
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if(resultCode == RESULT_OK) {
        // the image data
        Uri uri = data.getData();

        String[] projection = {MediaStore.Images.Media.DISPLAY_NAME};
        Cursor cursor = managedQuery(uri, projection, null, null, null);

        // the image Name
        String name = null;

        while (cursor != null && cursor.moveToNext()) {
            // here we get the name
            name = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DISPLAY_NAME));
        }

        // here to display image and it's name
        Toast.makeText(this, name, Toast.LENGTH_SHORT).show();
        imageView.setImageURI(uri);
    }
}

}
