RelativeLayout用代码实现布局
TextView txt1 = new TextView(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
params.addRule(RelativeLayout.LEFT_OF, 1001);
txt1.setLayoutParams(params);
TextView txt2 = new TextView(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams. WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params2.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
txt2.setLayoutParams(params2);
txt2.setText("obj");
txt2.setId(1001);
RelativeLayout layout1 = new RelativeLayout(this);
layout1.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
layout1.addView(txt1);
layout1.addView(txt2);
setContentView(layout1);
对应的XML:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<TextView
android:id="@+id/leftobj"
android:hint="left of the base"
android:layout_alignParentLeft="true"
android:layout_width="fill_parent"
android:layout_toLeftOf="@+id/base"
android:layout_height="wrap_content"></TextView>
<TextView
android:id="@+id/base"
android:text="obj"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"
android:layout_height="wrap_content"></TextView>
</RelativeLayout>
