如何根据数值更改第二个视图的长度。如果第一个数值为100，则宽度为match_parent。如果第二个数值为60，则如何根据该数值设置宽度。
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="20dp"
android:layout_below="@+id/headerproject">
<View
android:layout_width="match_parent"
android:layout_height="5dp"
android:background="@color/grey">
</View>
<View
android:layout_width="200dp"
android:layout_height="5dp"
android:background="@color/colorPrimary">
</View>
</RelativeLayout>

你可以使用 ProgressBar，但如果你真的需要继续这种方式，你可以像这样设置绿色条的宽度：
View viewGray, viewGreen;
int currentValue, totalValue;
//一些相关的代码
viewGray.postDelayed(new Runnable() {
@Override
public void run() {
int parentWidth = viewGray.getWidth();
int viewGrayWidth = (int)(parentWidth * (currentValue / (float)totalValue));
viewGreen.getLayoutParams().width = viewGrayWidth;
}
}, 50);
英文:
You can use a ProgressBar but if you really need to go on this way, you can set the green bar width like:
View viewGray, viewGreen;
int currentValue, totalValue;
//Some relevant code
viewGray.postDelayed(new Runnable() {
@Override
public void run() {
int parentWith = viewGray.getWidth();
int viewGrayWith = parentWith * (currentValue/(float)totalValue);
viewGreen.getLayoutParams().width = viewGrayWith;
}
},50);
