如何在下一个中显示文本和图像 activity

Question

我创建了 android 类似图库的应用，其中有一些使用 gridview 片段的图像。

功能正常，图像也显示在片段 gridview 和书籍中 activity 但文本未显示（文本未设置）

这是我的片段代码：

GridView grid;
    String[] web = {
            "Google",
            "Github",
            "Instagram",
            "Facebook",
            "Flickr",
            "Pinterest",
            "Quora",
            "Twitter",
            "Vimeo",
            "WordPress",
            "Youtube",
            "Stumbleupon",
            "SoundCloud",
            "Reddit",
            "Blogger"

    } ;
    int[] imageId = {
            R.drawable.person7,
            R.drawable.person1,
            R.drawable.person2,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7

    };
    int[] fullimg = {
            R.drawable.person7,
            R.drawable.person1,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7,
            R.drawable.person7

    };

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        setHasOptionsMenu(true);

        View view = inflater.inflate(R.layout.fragment_status,container,false);

        CustomGrid adapter = new CustomGrid(getActivity(), web, imageId, fullimg);

        //CustomGrid adapter = new CustomGrid(MainActivity.this, web, imageId);

        grid=(GridView) view.findViewById(R.id.grid);
        grid.setAdapter(adapter);
        grid.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {


                // Toast.makeText(MainActivity.this, "You Clicked at " +web[+ position], Toast.LENGTH_SHORT).show();



                String value=(String)grid.getItemAtPosition(i);
                Intent intent=new Intent(getActivity(),Book.class);
                intent.putExtra("web", web[i]);
                intent.putExtra("imageId", imageId[i]);
                intent.putExtra("fullimg", fullimg[i]);
                startActivity(intent);

            }
        });

        //return inflater.inflate(R.layout.fragment_status, container, false);
        return view;
    }

这是我的书 activity 代码，其中要显示文本和图像图片显示正常，但我不知道如何显示文字：

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


        TextView textView = (TextView) findViewById(R.id.txttitle);
        ImageView imageView = (ImageView)findViewById(R.id.imageView2);


        //textView.setText(txttitle);
        //textView.setText(web[i]);
        imageView.setImageResource(getIntent().getIntExtra("fullimg", R.drawable.person7));


    }

Answer 1

//textView.setText(txttitle);
//textView.setText(web[i]);
imageView.setImageResource(getIntent().getIntExtra("fullimg", R.drawable.person7));

您不会像检索图像那样检索传递的文本 ;)

Answer 2

只需从 Intent 中获取您的文本。我正在考虑 web 包含您的文本，然后下面的代码将为您获取文本

textView.setText(getIntent().getStringExtra("web"));

Answer 3

设置textview只是被注释掉了。只需将 TextView 设置为类似于 imageview:

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


    TextView textView = (TextView) findViewById(R.id.txttitle);
    ImageView imageView = (ImageView)findViewById(R.id.imageView2);


    textView.setText(getIntent().getStringExtra("web"))
    imageView.setImageResource(getIntent().getIntExtra("fullimg", R.drawable.person7));


}

Answer 4

不是通过 Intent 将变量传递给下一个 activity，而是使用应用程序 class 来存储数据并在应用程序中的任何地方使用。

Answer 5

在传递文本值时输入您要输入的常量 textView.setText(getIntent().getStringExtra("YourKeyValue"));
