如何用Java代码编写此xml

如何解决如何用Java代码编写此xml

| Android XML：

<TextView  
android:layout_width=\"fill_parent\" 
android:layout_height=\"wrap_content\" 
android:text=\"@string/hello\"
android:layout_height=\"28dp\" android:layout_width=\"180dp\"
android:layout_toRightOf=\"@+id/signinemailtxt\"
android:paddingLeft=\"50dp\"
android:layout_marginTop=\"65dp\"
android:background=\"#ffffff\" 

/>

Java：

layout=  new  RelativeLayout(this);
layout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
TextView Txt=new TextView(this);
Txt.setText(\"Name\");

如何在Java代码中获取layout_marginTop，layout_toRightOf选项     

解决方法

  RelativeLayout layout = new RelativeLayout(this);
TextView tv1 = new TextView(this);
tv1.setText(\"A\");

TextView tv2 = new TextView(this);
tv2.setText(\"B\");
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.FILL_PARENT);
lp.addRule(RelativeLayout.RIGHT_OF,tv1.getId());

layout.addView(tv1);        
layout.addView(tv2,lp);

    ,对于layout_margin：

LayoutParams params = new LayoutParams(context,attrs);
params.setMargins(0,5,5); //setMargins (int left,int top,int right,int bottom)

Txt.setLayoutParams(params);

    ,不要声明布局和文本视图的新实例，而是获取您在xml中创建的实例：

RelativeLayout layout = (RelativeLayout) findViewById(R.id.LayoutId);
TextView Txt = (TextView) findViewById(R.id.TextViewId);

现在，您可以编辑在屏幕上看到的布局和文本视图。
