Question

/ / 我正在使用ACTION_VIEW打开图片网址。以下是代码

ImageView _presImage1= (ImageView) view_local.findViewById(R.id.img_prescription1);
    Picasso.with(this.getContext()).load(img_url).placeholder(R.mipmap.ic_launcher).into(_presImage1);

    _presImage1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent=new Intent();
            intent.setAction(Intent.ACTION_VIEW);
            Log.i("ABHINAY","Image is clicked:" + img_url);
            intent.setDataAndType(Uri.parse(img_url),"image/*");
            startActivity(intent);
        }
    });

但是点击时图像没有打开。传递的网址有效，并在浏览器中正常打开。

以下是我正在使用的xml文件

以下是Java函数

private void addPrescriptionChilddouble(final String img_url, String name, String created_date, final String img_url1, String name1, String created_date1) {
    LayoutInflater li= (LayoutInflater)getActivity().getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    LinearLayout ll= (LinearLayout)view.findViewById(R.id.parentMedicalHistory);
    final View view_local=li.inflate(R.layout.fragment_medical_history_child_double, null);

    //FIRST
    TextView doctor_name=(TextView) view_local.findViewById(R.id.doctor_name);
    TextView date_created=(TextView) view_local.findViewById(R.id.prescription_date);

    int count=ll.getChildCount();count++;
    doctor_name.setText(name);
    date_created.setText(created_date);
    ImageView _presImage1= (ImageView) view_local.findViewById(R.id.img_prescription1);
    Picasso.with(this.getContext()).load(img_url).placeholder(R.mipmap.ic_launcher).into(_presImage1);

    _presImage1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent=new Intent();
            intent.setAction(Intent.ACTION_VIEW);
            Log.i("ABHINAY","Image is clicked:" + img_url);
            intent.setDataAndType(Uri.parse(img_url),"image/*");
            startActivity(intent);
        }
    });

    //SECOND
    TextView doctor_name1=(TextView) view_local.findViewById(R.id.doctor_name1);
    TextView date_created1=(TextView) view_local.findViewById(R.id.prescription_date1);

    doctor_name1.setText(name1);
    date_created1.setText(created_date1);
    ImageView _presImage2= (ImageView) view_local.findViewById(R.id.img_prescription2);
    Picasso.with(this.getContext()).load(img_url1).placeholder(R.mipmap.ic_launcher).into(_presImage2);

    _presImage2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent=new Intent();
            intent.setAction(Intent.ACTION_VIEW);
            Log.i("ABHINAY", "Image is clicked:" + img_url1);
            intent.setDataAndType(Uri.parse(img_url1),"image/*");
            startActivity(intent);
        }
    });

    ll.addView(view_local);
}

如果图片位于http://images.all-free-download.com/images/graphiclarge/daisy_pollen_flower_220533.jpg等远程网址中，请在OnClickListener()中使用此代码：

String url = "http://images.all-free-download.com/images/graphiclarge/daisy_pollen_flower_220533.jpg";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

但是如果您尝试显示属于资源文件夹等本地资源的图片，则无法在浏览中显示该图像，您可以通过使用WebView来显示图像！

打开网址的ACTION_VIEW不起作用
