Question

我需要将这三个文本和一个图像一个接一个地水平放置。怎么办？

我的代码如下：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_placeorder,
            container, false);
    ScrollView scrl=new ScrollView(getActivity());
     final LinearLayout ll=new LinearLayout(getActivity());
     ll.setOrientation(LinearLayout.VERTICAL);
     scrl.addView(ll);
     for(int i=0;i<3;i++) {
     // TODO Auto-generated method stub
     TextView time=new TextView(getActivity());
     time.setText("07.23"+i);
     ll.addView(time);
    TextView orderId=new TextView(getActivity());
     orderId.setText("ORDER:03987"+i);
     ll.addView(orderId); 
     TextView dollarPrice = new TextView(getActivity());
     dollarPrice.setText("$39.55"+i);
     ll.addView(dollarPrice); 
     ImageView image = new ImageView(getActivity());
     image.setImageResource(R.drawable.arrow_right); 
     ll.addView(image);
     }

Answer 1

您不需要动态创建所有视图。只需为项目创建xml并在循环内膨胀它。像..

<强> MainActivity.java

public class MainActivity extends Activity {

    private LinearLayout layoutmain;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        layoutmain = (LinearLayout) findViewById(R.id.layoutmain);
        for (int i = 0; i <= 3; i++) {
            View viewToLoad = LayoutInflater.from(MainActivity.this).inflate(
                    R.layout.row, null);
            ((LinearLayout) findViewById(R.id.layoutmain)).addView(viewToLoad);
        }

TextView txt = new TextView(MainActivity.this);
    txt.setText("Ship");
    ((LinearLayout) findViewById(R.id.layoutmain)).addView(txt);

    for (int i = 0; i <= 3; i++) {

        View viewToLoad = LayoutInflater.from(MainActivity.this).inflate(
                R.layout.row, null);
        ((LinearLayout) findViewById(R.id.layoutmain)).addView(viewToLoad);
    }
    }
}

<强> activity_main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="PROCESSED" />

    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <LinearLayout
            android:id="@+id/layoutmain"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >
        </LinearLayout>
    </ScrollView>
</LinearLayout>

<强> row.xml

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

    <TextView
        android:id="@+id/txtfirst"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="07.23" />

    <TextView
        android:id="@+id/txtsecond"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="ORDER:0378945" />

    <TextView
        android:id="@+id/txtthird" android:gravity="center"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="$36.55" />

</LinearLayout>

您可以使用方向为Horizontal的另一个LinearLayout，并将其设置为垂直LinearLayout。这样你的卷轴就不会受到影响。

这样的事情：

View view = inflater.inflate(R.layout.fragment_placeorder,
            container, false);
ScrollView scrl=new ScrollView(getActivity());
LinearLayout ll=new LinearLayout(getActivity());
ll.setOrientation(LinearLayout.VERTICAL);

for(int i=0;i<3;i++) {
    // TODO Auto-generated method stub
    LinearLayout l2=new LinearLayout(getActivity());
    l2.setOrientation(LinearLayout.HORIZONTAL);
    TextView time=new TextView(getActivity());
    time.setText("07.23"+i);
    l2.addView(time);
    TextView orderId=new TextView(getActivity());
    orderId.setText("ORDER:03987"+i);
    l2.addView(orderId);
    TextView dollarPrice = new TextView(getActivity());
    dollarPrice.setText("$39.55"+i);
    l2.addView(dollarPrice);
    ImageView image = new ImageView(getActivity());
    image.setImageResource(R.drawable.arrow_right);
    l2.addView(image);
    l1.addView(l2);
}
scrl.addView(ll);

这将在主外部布局中添加一个新的线性布局，其中3个textview和imageview在一行中，它将是垂直的，可滚动的。

希望这有帮助。

在你的xml布局中添加水平LinearLayout并将你的对象放在上面：

 <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
    android:orientation="horizontal">
    <TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView"/>
    <TextView
    android:id="@+id/textView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView" />
     <TextView
    android:id="@+id/textView3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView" />
</LinearLayout>

并在您的班级中将此布局设置为水平或垂直，如下所示：

LinearLayout m =(LinearLayout) findViewById(R.id.LinearLayout1);
m.setOrientation(LinearLayout.HORIZONTAL);
