android-layout - 如何以编程方式更改框架布局的高度和宽度？

Question

我是安卓新手。

我面临一个问题，即我正在向我的应用程序添加框架布局，代码是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <FrameLayout android:id="@+id/frameLayout1">
        <LinearLayout 
        android:layout_height="wrap_content" 
        android:id="@+id/linearLayout1" 
        android:layout_width="fill_parent">
        </LinearLayout>
    </FrameLayout>
</LinearLayout>

我的问题是我想改变不同屏幕方向的框架布局高度

示例代码是

    wm = (WindowManager)getSystemService(Context.WINDOW_SERVICE);

            getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

            Log.v("height","height"+wm.getDefaultDisplay().getHeight());

            if(wm.getDefaultDisplay().getHeight() <= 427)
             {
                 Log.v("height","111");


((FrameLayout)findViewById(R.id.frameLayout1)).setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
         }
        else
        {
            ((FrameLayout)findViewById(R.id.frameLayout1)).setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
        }

但它给力接近，

如果有人有想法，请帮助我。

提前致谢。

你必须使用 LinearLayout.LayoutParams (int width, int height, float weight)

FrameLayout frameLayout = new FrameLayout(context);
LinearLayout.LayoutParams layPra = new LinearLayout.LayoutParams(width,height,mWeight);
layPra .gravity = Gravity.CENTER | Gravity.BOTTOM;
frameLayout .setLayoutParams(layPra );
