如何在Android Studio中创建自定义图像按钮？

Question

如何在Android Studio中创建像这样的图像按钮？ 需要依赖吗？ 还是还有其他方法？

Answer 1

可以通过多种方式来完成。 它仅取决于您如何自定义布局。 你可以这样做...

1-带有白色背景的线性布局，里面有1个图像视图和1个textview ...

2-使用带有图像视图和文本视图的框架布局。

3-图像中的视图是带有cardviews的回收者视图。 要使用回收站和存储卡，您需要支持设计依赖性。

// RecyclerView
compile 'com.android.support:recyclerview-v7:23.3.+'

// CardView
compile 'com.android.support:cardview-v7:23.3.+'

Answer 2

您必须将回收视图与cardview一起使用。

要在您的应用程序中使用CardView，请在build.gradle中添加CardView依赖项并同步项目。

    dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.android.support:design:23.3.0'
     // RecyclerView
    compile 'com.android.support:recyclerview-v7:23.3.+'
     // CardView
    compile 'com.android.support:cardview-v7:23.3.+'
     // Glide
    compile 'com.github.bumptech.glide:glide:3.7.0'
}

之后，您创建一个xml卡视图

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.v7.widget.CardView
        android:id="@+id/card_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:layout_margin="@dimen/card_margin"
        android:elevation="3dp"
        card_view:cardCornerRadius="@dimen/card_album_radius">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <ImageView
                android:id="@+id/thumbnail"
                android:layout_width="match_parent"
                android:layout_height="@dimen/album_cover_height"
                android:background="?attr/selectableItemBackgroundBorderless"
                android:clickable="true"
                android:scaleType="fitXY" />

            <TextView
                android:id="@+id/title"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_below="@id/thumbnail"
                android:paddingLeft="@dimen/album_title_padding"
                android:paddingRight="@dimen/album_title_padding"
                android:paddingTop="@dimen/album_title_padding"
                android:textColor="@color/album_title"
                android:textSize="@dimen/album_title" />

            <TextView
                android:id="@+id/count"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_below="@id/title"
                android:paddingBottom="@dimen/songs_count_padding_bottom"
                android:paddingLeft="@dimen/album_title_padding"
                android:paddingRight="@dimen/album_title_padding"
                android:textSize="@dimen/songs_count" />

            <ImageView
                android:id="@+id/overflow"
                android:layout_width="@dimen/ic_album_overflow_width"
                android:layout_height="@dimen/ic_album_overflow_height"
                android:layout_alignParentRight="true"
                android:layout_below="@id/thumbnail"
                android:layout_marginTop="@dimen/ic_album_overflow_margin_top"
                android:scaleType="centerCrop"
                android:src="@drawable/ic_dots" />

        </RelativeLayout>

    </android.support.v7.widget.CardView>

</LinearLayout>

然后，您可以为此创建适配器

    public class AlbumsAdapter extends RecyclerView.Adapter<AlbumsAdapter.MyViewHolder> {

    private Context mContext;
    private List<Album> albumList;

    public class MyViewHolder extends RecyclerView.ViewHolder {
        public TextView title, count;
        public ImageView thumbnail, overflow;

        public MyViewHolder(View view) {
            super(view);
            title = (TextView) view.findViewById(R.id.title);
            count = (TextView) view.findViewById(R.id.count);
            thumbnail = (ImageView) view.findViewById(R.id.thumbnail);
            overflow = (ImageView) view.findViewById(R.id.overflow);
        }
    }


    public AlbumsAdapter(Context mContext, List<Album> albumList) {
        this.mContext = mContext;
        this.albumList = albumList;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.album_card, parent, false);

        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, int position) {
        Album album = albumList.get(position);
        holder.title.setText(album.getName());
        holder.count.setText(album.getNumOfSongs() + " songs");

        // loading album cover using Glide library
        Glide.with(mContext).load(album.getThumbnail()).into(holder.thumbnail);

        holder.overflow.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showPopupMenu(holder.overflow);
            }
        });
    }

    /**
     * Showing popup menu when tapping on 3 dots
     */
    private void showPopupMenu(View view) {
        // inflate menu
        PopupMenu popup = new PopupMenu(mContext, view);
        MenuInflater inflater = popup.getMenuInflater();
        inflater.inflate(R.menu.menu_album, popup.getMenu());
        popup.setOnMenuItemClickListener(new MyMenuItemClickListener());
        popup.show();
    }

    /**
     * Click listener for popup menu items
     */
    class MyMenuItemClickListener implements PopupMenu.OnMenuItemClickListener {

        public MyMenuItemClickListener() {
        }

        @Override
        public boolean onMenuItemClick(MenuItem menuItem) {
            switch (menuItem.getItemId()) {
                case R.id.action_add_favourite:
                    Toast.makeText(mContext, "Add to favourite", Toast.LENGTH_SHORT).show();
                    return true;
                case R.id.action_play_next:
                    Toast.makeText(mContext, "Play next", Toast.LENGTH_SHORT).show();
                    return true;
                default:
            }
            return false;
        }
    }

    @Override
    public int getItemCount() {
        return albumList.size();
    }
}

这是活动main.xml

                    <TextView

            <android.support.v7.widget.Toolbar

    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_main" />

</android.support.design.widget.CoordinatorLayout>

这是content_main.xml

        android:layout_height="wrap_content"
        android:clipToPadding="false"
        android:scrollbars="vertical" />

</RelativeLayout>

之后，最后编写MainActivity

    public class MainActivity extends AppCompatActivity {

    private RecyclerView recyclerView;
    private AlbumsAdapter adapter;
    private List<Album> albumList;

        initCollapsingToolbar();

        recyclerView = (RecyclerView) findViewById(R.id.recycler_view);

        albumList = new ArrayList<>();
        adapter = new AlbumsAdapter(this, albumList);

        RecyclerView.LayoutManager mLayoutManager = new GridLayoutManager(this, 2);
        recyclerView.setLayoutManager(mLayoutManager);
        recyclerView.addItemDecoration(new GridSpacingItemDecoration(2, dpToPx(10), true));
        recyclerView.setItemAnimator(new DefaultItemAnimator());
        recyclerView.setAdapter(adapter);

        prepareAlbums();

        try {
            Glide.with(this).load(R.drawable.cover).into((ImageView) findViewById(R.id.backdrop));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**

        // hiding & showing the title when toolbar expanded & collapsed
        appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
            boolean isShow = false;
            int scrollRange = -1;

            @Override
            public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
                if (scrollRange == -1) {

                    collapsingToolbar.setTitle(" ");
                    isShow = false;
