我有一个Flow布局,显示行的4个对象,但我需要显示这4个对象,每个对象下面都有一个textview。但它显示2个图像和2个textview,并显示junp到另一行。我尝试创建一个ViewGroup来一起显示它们,但我得到了同样的结论。也许如果我尝试在组内部设置textView的位置运河工作,但我不知道怎么做。
我的XML:
<ScrollView
android:id="@+id/svLikes"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginBottom="60dp"
android:layout_marginEnd="14dp"
android:layout_marginStart="14dp"
android:layout_marginTop="48dp"
android:background="#3c4052"
android:orientation="vertical"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="@+id/btnAdd"
app:layout_constraintVertical_bias="0.0"
tools:layout_constraintBottom_creator="1"
tools:layout_constraintLeft_creator="1"
tools:layout_constraintRight_creator="1"
tools:layout_constraintTop_creator="1">
<com.nex3z.flowlayout.FlowLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="5dp"
android:paddingRight="5dp"
app:childSpacingForLastRow="align"
android:paddingLeft="5dp"
app:rowSpacing="8dp"
android:id="@+id/likesContainer"
>
</com.nex3z.flowlayout.FlowLayout>
</ScrollView>
我的代码:
ImageView iconLike = new ImageView(Register30.this);
TextView txtLike = new TextView(Register30.this);
iconLike.setImageDrawable(getDrawable(R.drawable.x));
txtLike.setText("Unable");
countLikesAdd++;
removeMessageOrShow();
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(140,130);
lp.setMargins(5,5,5,5);
iconLike.setLayoutParams(lp);
txtLike.setLayoutParams(lp);
txtLike.setTextColor(Color.parseColor("#FFFFFF"));
fieldLike.setText("");
ViewGroup gp = new LinearLayout(Register30.this);
gp.addView(iconLike);
gp.addView(txtLike);
likesContainer.addView(gp);

第一种方法:静态方式 我认为你需要的是TextView上的可绘制图像。可绘制图像可以插入除中心之外的任何位置。从asset studio创建所需大小的合适图像,并在TextView上使用此行。
机器人:drawableTop = “@绘制/ ic_fb_logo_blue_48dp”
下面的代码中写了一个简单的实现。
<android.support.v4.widget.NestedScrollView
android:id="@+id/svLikes"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="60dp"
android:layout_marginEnd="14dp"
android:layout_marginStart="14dp"
android:layout_marginTop="48dp"
android:orientation="vertical">
<com.nex3z.flowlayout.FlowLayout
android:id="@+id/likesContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="5dp"
android:paddingRight="5dp"
android:paddingTop="5dp"
app:childSpacingForLastRow="align"
app:rowSpacing="8dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="@drawable/ic_fb_logo_blue_48dp"
android:gravity="center"
android:text="@string/facebook"
android:textSize="16sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="@drawable/ic_fb_logo_blue_48dp"
android:gravity="center"
android:text="@string/facebook"
android:textSize="16sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="@drawable/ic_fb_logo_blue_48dp"
android:gravity="center"
android:text="@string/facebook"
android:textSize="16sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="@drawable/ic_fb_logo_blue_48dp"
android:gravity="center"
android:text="@string/facebook"
android:textSize="16sp" />
</com.nex3z.flowlayout.FlowLayout>
</android.support.v4.widget.NestedScrollView>
输出图像如下。我使用NestedScrollView而不是ScrollView。
第二种方法:动态 以编程方式,可以使用网格布局生成许多视图。我使用recylerview实现的是
Inside Activity类:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
recyclerOne = (RecyclerView) findViewById(R.id.recyclerView);
initRecyclerView();
//update whenever necessary
adapterOne.updateItems(myList);
}
private void initRecyclerView(){
//Datum is model class
int spanCount = 4; // 4 columns in grid
int spacing = 8;
boolean includeEdge = true;
GridLayoutManager gridLayoutManager = new GridLayoutManager(mContext, spanCount);
recyclerOne.setHasFixedSize(false);
recyclerOne.setLayoutManager(gridLayoutManager);
recyclerOne.addItemDecoration(new GridSpacingItemDecoration(spanCount, spacing, includeEdge));
adapterOne = new RecylcerViewAdapter(new ArrayList<Datum>());
recyclerOne.setAdapter(adapterOne);
}
GridSpacingItemDecoration 类是
public class GridSpacingItemDecoration extends RecyclerView.ItemDecoration {
private int spanCount;
private int spacing;
private boolean includeEdge;
public GridSpacingItemDecoration(int spanCount, int spacing, boolean includeEdge) {
this.spanCount = spanCount;
this.spacing = spacing;
this.includeEdge = includeEdge;
}
@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
int position = parent.getChildAdapterPosition(view); // item position
int column = position % spanCount; // item column
if (includeEdge) {
outRect.left = spacing - column * spacing / spanCount; // spacing - column * ((1f / spanCount) * spacing)
outRect.right = (column + 1) * spacing / spanCount; // (column + 1) * ((1f / spanCount) * spacing)
if (position < spanCount) { // top edge
outRect.top = spacing;
}
outRect.bottom = spacing; // item bottom
} else {
outRect.left = column * spacing / spanCount; // column * ((1f / spanCount) * spacing)
outRect.right = spacing - (column + 1) * spacing / spanCount; // spacing - (column + 1) * ((1f / spanCount) * spacing)
if (position >= spanCount) {
outRect.top = spacing; // item top
}
}
}
}
在回收站视图适配器类中,在绑定视图期间,使用单个textview和可绘制图像,如第一种方法和更新数据。要更新整个列表,请创建以下函数并从活动类中调用它:
public void updateItems(List<Datum> data) {
list.clear()
list.addAll(data)
notifyDataSetChanged();
}
其他方法 还有另外一种我知道的方法是通过给项目充气并在已经创建的linearlayout(或任何其他容器布局)上添加膨胀的视图来完成。
使用您喜欢的任何方法。享受编码!

试试这个,这些是静态数据
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<LinearLayout
android:layout_width="80dp"
android:layout_height="80dp"
android:orientation="vertical">
<ImageView
android:id="@+id/imageView4"
android:layout_width="match_parent"
android:layout_height="60dp"
android:src="@android:drawable/btn_star" />
<TextView
android:id="@+id/textView9"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="TextView" />
</LinearLayout>
<LinearLayout
android:layout_width="80dp"
android:layout_height="80dp"
android:orientation="vertical">
<ImageView
android:id="@+id/img2"
android:layout_width="match_parent"
android:layout_height="60dp"
android:src="@android:drawable/btn_star" />
<TextView
android:id="@+id/tekxjtView9"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="TextView" />
</LinearLayout>
<LinearLayout
android:layout_width="80dp"
android:layout_height="80dp"
android:orientation="vertical">
<ImageView
android:id="@+id/img3"
android:layout_width="match_parent"
android:layout_height="60dp"
android:src="@android:drawable/btn_star" />
<TextView
android:id="@+id/txt3"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="TextView" />
</LinearLayout>
</LinearLayout>
用于动态数据使用 gridlayout并使用上面的代码作为适配器布局
