java - Android 结合两个 LayoutParams

Question

我正在尝试使用布局参数修复 ProgressBar 的宽度和边距

以下正确设置layout_margin

int finalHeight = soundcloudImage.getHeight() / 8;
int finalWidth = soundcloudImage.getWidth() / 4;

RelativeLayout.LayoutParams progressParams = (RelativeLayout.LayoutParams)progressBar.getLayoutParams();

progressParams.setMargins(0, 0, 0, finalHeight);

progressBar.setLayoutParams(progressParams);

这样就成功设置了Layout_Width

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(finalWidth*2, 20);

progressBar.setLayoutParams(params);

但是我似乎无法合并该声明以使它们一起工作

这是布局 xml

<RelativeLayout
                android:id="@+id/relativelayout"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >

                <ImageView
                    android:id="@+id/imageView"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:src="@drawable/soundcloudimage" />

                <TextView
                    android:id="@+id/myImageViewText"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_alignBottom="@+id/imageView"
                    android:textSize="20dp"
                    android:layout_centerHorizontal="true"
                    android:text=""
                    android:textColor="#EA4F17" />

                <ProgressBar
                    android:id="@+id/progressBar"
                    style="?android:attr/progressBarStyleHorizontal"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_alignBottom="@+id/imageView"
                    android:layout_alignLeft="@+id/imageView"
                    android:layout_alignParentRight="true" />

            </RelativeLayout>

任何帮助都会很棒

编辑:尝试了以下操作

RelativeLayout.LayoutParams progressParams = (RelativeLayout.LayoutParams)progressBar.getLayoutParams();
progressParams.width=finalWidth*2;
progressParams.height= 20;
progressParams.setMargins(0, 0, 0, finalHeight);

progressBar.setLayoutParams(progressParams);

结果是这样的

编辑:也尝试过这个:

RelativeLayout.LayoutParams progressParams = new RelativeLayout.LayoutParams(finalWidth*2, 20);
progressParams.setMargins(0, 0, 0, finalHeight);    
progressBar.setLayoutParams(progressParams);

它创建了这个

Answer 1

RelativeLayout.LayoutParams progressParams = (RelativeLayout.LayoutParams)progressBar.getLayoutParams();
progressParams.width=finalWidth*2;
progressParams.height= 20;
progressParams.setMargins(finalWidth, 0, finalWidth, finalHeight);

progressBar.setLayoutParams(progressParams);

试试这个:

RelativeLayout.LayoutParams progressParams = new RelativeLayout.LayoutParams(finalWidth*2, 20);
progressParams.setMargins(0, 0, 0, finalHeight);    
progressBar.setLayoutParams(progressParams);
