Android 如何添加右上角带有十字按钮的动态图像视图

我想在应用程序中提供附件功能。请参阅附加屏幕截图

如何在Android中创建专业语法

您应该创建一个包含两个ImageView的frameLayout，一个包含实际图像，另一个包含十字

创建包含框架布局的自定义_view.xml

 <?xml version="1.0" encoding="utf-8"?>
    <FrameLayout
    ....>
    <ImageView/>
    <ImageView/>

    </FrameLayout>

正如我所看到的，你问题的解决办法。首先创建视图的

XML

布局。然后创建类，该类将使用

GET

方法膨胀到它中。然后通过代码创建此

视图

，并添加到容器中

layout_custom.xml： 最后，该员工的使用：

final CustomView customView1 = new CustomView(getBaseContext());
final CustomView customView2 = new CustomView(getBaseContext());
final LinearLayout container = (LinearLayout) findViewById(R.id.container);
container.addView(customView1);
container.addView(customView2);

但我不想在警报对话框中显示这些附件，我想在活动屏幕中显示它们我必须动态创建框架布局？请查看编辑，您也可以使用RelativeLayout btw

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout android:id="@+id/root"
             xmlns:android="http://schemas.android.com/apk/res/android"
             android:layout_width="200dp"
             android:layout_height="150dp">

    <ImageView
        android:id="@+id/img_photo"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="12dp"
        android:background="#000"/>

    <ImageButton
        android:id="@+id/btn_close"
        android:layout_width="35dp"
        android:layout_height="35dp"
        android:layout_gravity="end"
        android:background="#00000000"
        android:scaleType="fitXY"
        android:src="@drawable/temp_close"/>

</FrameLayout>

public class CustomView extends FrameLayout {

    private View mRoot;
    private ImageView mImgPhoto;
    private View mBtnClose;

    private Context mContext;

    public CustomView(final Context context) {
        this(context, null);
    }

    public CustomView(final Context context, final AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public CustomView(final Context context, final AttributeSet attrs, final int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(context);
    }

    private void init(final Context context) {
        if (isInEditMode())
            return;

        final LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View customView = null;

        if (inflater != null)
            customView = inflater.inflate(R.layout.layout_custom, this);

        if (customView == null)
            return;

        mRoot = customView.findViewById(R.id.root);
        mImgPhoto = (ImageView) customView.findViewById(R.id.img_photo);
        mBtnClose = customView.findViewById(R.id.btn_close);
    }

    public View getRoot() {
        return mRoot;
    }

    public ImageView getImgPhoto() {
        return mImgPhoto;
    }

    public View getBtnClose() {
        return mBtnClose;
    }
}

final CustomView customView1 = new CustomView(getBaseContext());
final CustomView customView2 = new CustomView(getBaseContext());
final LinearLayout container = (LinearLayout) findViewById(R.id.container);
container.addView(customView1);
container.addView(customView2);
