我有一个linearLayout_child里面另一个linearLayout_parent。

我想linearLayout_child与父母的权利保持一致。

我怎样才能做到这一点？

如果我希望所有linearLayout_parent的孩子都与父母的权利保持一致怎么办？

我想以编程方式完成它们。

更新

是否有任何工具可以让我在我的活动视图中查看当前布局属性和属性？该代码更改了原始 XMl 的许多属性，并且在特定情况下很难遵循。

这是我的xml：

        <MyTextView
            android:id="@+id/navBarDistance"
            style="@style/NavBarDistance"
            android:textSize="19dp"
            android:text="miles"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            />

        <MyTextView
            android:id="@+id/navBarDistanceUnit"
            style="@style/NavBarDistUnit"
            android:textSize="19dp"
            android:text="0.1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="3dp" 
            />
    </LinearLayout>
        <LinearLayout
            android:id="@+id/navBarDistanceLayoutRtl"
            android:layout_width="70dp"
            android:layout_height="match_parent"
            android:layout_marginRight="8dp"
            android:layout_marginTop="5dp"
            android:gravity="center_vertical|right"
            android:orientation="horizontal"
            android:visibility="gone">

            <MyTextViewType
                android:id="@+id/navBarDistanceUnitRtl"
                style="@style/NavBarDistUnit"
                android:textSize="19dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginRight="3dp"
                />

            <MyTextViewType
                android:id="@+id/navBarDistanceRtl"
                style="@style/NavBarDistance"
                android:textSize="19dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                />
        </LinearLayout>
</LinearLayout>

这是部分代码：

更改为 AlerterMode 然后返回到 non-alrter more 使得navBarDistanceLayoutRtl左对齐而不是右对齐

            if (bIsAlertMode)
            {

...
                if (rtlMode)
                {
                    width = view.findViewById(R.id.navBarDistanceLayoutRtl).getWidth();
                    android.widget.LinearLayout.LayoutParams DistanceBar = new LinearLayout.LayoutParams(width, android.widget.LinearLayout.LayoutParams.MATCH_PARENT);
                    DistanceBar.setMargins(3, 20, 3, 0);
                    view.findViewById(R.id.navBarDistanceLayoutRtl).setLayoutParams(DistanceBar);
                }
                else
                {
                    width = view.findViewById(R.id.navBarDistanceLayout).getWidth();
                    android.widget.LinearLayout.LayoutParams DistanceBar = new LinearLayout.LayoutParams(width, android.widget.LinearLayout.LayoutParams.MATCH_PARENT);
                    DistanceBar.setMargins(3, 20, 3, 0);
                    view.findViewById(R.id.navBarDistanceLayout).setLayoutParams(DistanceBar);

                }

...

            }
            else
            {
   ...

                if (rtlMode)
                {
                    width = view.findViewById(R.id.navBarDistanceLayoutRtl).getWidth();
                    android.widget.LinearLayout.LayoutParams DistanceBar = new LinearLayout.LayoutParams(width, android.widget.LinearLayout.LayoutParams.WRAP_CONTENT);
                    DistanceBar.setMargins(20, 8, 3, 0);

                    DistanceBar.gravity = RelativeLayout.ALIGN_PARENT_RIGHT;

                    view.findViewById(R.id.navBarDistanceLayoutRtl).setLayoutParams(DistanceBar);

                    view.findViewById(R.id.navBarDistanceLayoutRtl).setVisibility(View.VISIBLE);
                    view.findViewById(R.id.navBarDistanceLayout).setVisibility(View.GONE);
                    distance = (TextView)view.findViewById(R.id.navBarDistanceRtl);
                    distanceUnit = (TextView)view.findViewById(R.id.navBarDistanceUnitRtl);
                }
                else
                {
                    width = view.findViewById(R.id.navBarDistanceLayout).getWidth();
                    android.widget.LinearLayout.LayoutParams DistanceBar = new LinearLayout.LayoutParams(width, android.widget.LinearLayout.LayoutParams.WRAP_CONTENT);
                    DistanceBar.setMargins(0, 8, 3, 0);
                    view.findViewById(R.id.navBarDistanceLayout).setLayoutParams(DistanceBar);

                    DistanceBar.gravity = RelativeLayout.ALIGN_PARENT_LEFT;

                    view.findViewById(R.id.navBarDistanceLayoutRtl).setVisibility(View.GONE);
                    view.findViewById(R.id.navBarDistanceLayout).setVisibility(View.VISIBLE);
                    distance = (TextView)view.findViewById(R.id.navBarDistance);
                    distanceUnit = (TextView)view.findViewById(R.id.navBarDistanceUnit);

                }

                ...
            }
        }

试着这样设置gravity..

        LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.MATCH_PARENT);

    layoutParams.gravity = RelativeLayout.ALIGN_PARENT_RIGHT;

    linearlayout.setLayoutParams(layoutParams);

您可以使用：

  • 布局参数GRAVITY Doc
  • 间隔视图（设置layout_width="0dp"和layout_weight="1"的简单视图

我在我的案例中找到了一个解决方案，我将 Views 添加到 a Linear Layout，只需设置gravity为TEXT_ALIGNMENT_VIEW_START:

    LinearLayout row = new LinearLayout(Control.this);
    row.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT));
    row.setGravity(View.TEXT_ALIGNMENT_VIEW_START);
