Question

我有使用relativelayout的av xml文件，它工作正常，现在我希望它转换为程序化形式，我的xml是..

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >


<TextView
    android:id="@+id/b"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/a"
    android:layout_alignParentLeft="true"
    android:text="" />    

<TextView
    android:id="@+id/d"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text=""
    android:layout_toRightOf="@+id/b"/>

 <TextView
    android:id="@+id/c"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text=""
    android:layout_below="@+id/b"/>    

<TextView
    android:id="@+id/a"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/d"
    android:layout_below="@+id/d"
    android:text="" />

<TextView
    android:id="@+id/e"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text=""
    android:layout_below="@+id/c"/>

<TextView
    android:id="@+id/f"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/e"
    android:layout_alignBottom="@+id/e"
    android:layout_alignLeft="@+id/a"
    android:text="" />

</RelativeLayout>

请给我一些想法如何将其转换为程序化..我试图转换为以程序化形式编写，但我不知道addrule ..指导我..

Answer 1

按照以下代码添加规则：

    LinearLayout linearLayout = new LinearLayout(this);
    RelativeLayout.LayoutParams relativeParams = new     RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    parentView.addView(linearLayout, layoutParams);

请尝试这种方式，希望这有助于您解决问题。

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    RelativeLayout relativeLayout =  new RelativeLayout(this);
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    relativeLayout.setLayoutParams(layoutParams);

    TextView textViewB = new TextView(this);
    textViewB.setId(1);
    textViewB.setText("b");
    RelativeLayout.LayoutParams layoutParamsB = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParamsB.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    layoutParamsB.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
    textViewB.setLayoutParams(layoutParamsB);


    TextView textViewD = new TextView(this);
    textViewD.setId(2);
    textViewD.setText("d");
    RelativeLayout.LayoutParams layoutParamsD = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParamsB.addRule(RelativeLayout.ALIGN_PARENT_TOP);
    layoutParamsD.addRule(RelativeLayout.RIGHT_OF,textViewB.getId());
    textViewD.setLayoutParams(layoutParamsD);


    TextView textViewC = new TextView(this);
    textViewC.setId(3);
    textViewC.setText("c");
    RelativeLayout.LayoutParams layoutParamsC = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParamsC.addRule(RelativeLayout.BELOW,textViewB.getId());
    layoutParamsC.addRule(RelativeLayout.ALIGN_LEFT);
    textViewC.setLayoutParams(layoutParamsC);


    TextView textViewA = new TextView(this);
    textViewA.setId(4);
    textViewA.setText("a");
    RelativeLayout.LayoutParams layoutParamsA = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParamsA.addRule(RelativeLayout.BELOW,textViewD.getId());
    layoutParamsA.addRule(RelativeLayout.RIGHT_OF,textViewC.getId());
    textViewA.setLayoutParams(layoutParamsA);


    TextView textViewE = new TextView(this);
    textViewE.setId(5);
    textViewE.setText("e");
    RelativeLayout.LayoutParams layoutParamsE = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParamsE.addRule(RelativeLayout.BELOW,textViewC.getId());
    layoutParamsE.addRule(RelativeLayout.ALIGN_LEFT);
    textViewE.setLayoutParams(layoutParamsE);


    TextView textViewF = new TextView(this);
    textViewF.setId(6);
    textViewF.setText("f");
    RelativeLayout.LayoutParams layoutParamsF = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    layoutParamsF.addRule(RelativeLayout.BELOW,textViewA.getId());
    layoutParamsF.addRule(RelativeLayout.RIGHT_OF,textViewE.getId());
    textViewF.setLayoutParams(layoutParamsF);

    relativeLayout.addView(textViewB);
    relativeLayout.addView(textViewD);
    relativeLayout.addView(textViewC);
    relativeLayout.addView(textViewA);
    relativeLayout.addView(textViewE);
    relativeLayout.addView(textViewF);

    setContentView(relativeLayout);
}

仅供参考，您不应该（并且您不被允许）询问任何工具或资源。

但是，我知道一个工具可以用来为你的XML布局生成Java代码，Android Layout Finder。在这个Web工具中，您只需要粘贴XML，选择适当的选项，它将为您提供Java代码。
