Question

我需要动态创建代表这个xml代码的LinearLayout：

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#ddd"
    android:orientation="vertical"
    android:padding="1dp" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#fff"
        android:orientation="horizontal"
        android:paddingBottom="26dp"
        android:paddingTop="26dp" >

        <LinearLayout
            android:layout_width="160dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="#fff" >

            <ImageView
                android:id="@+id/ImageView04"
                android:layout_width="48dp"
                android:layout_height="48dp"
                android:layout_gravity="top"
                android:layout_marginLeft="32dp"
                android:layout_marginTop="4dp"
                android:background="#eee" />
        </LinearLayout>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="#fff"
            android:orientation="vertical" >

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="top"
                android:gravity="top"
                android:paddingBottom="4dp"
                android:paddingLeft="16dp"
                android:text="Name of event"
                android:textSize="22sp" />

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:paddingLeft="16dp"
                android:text="Group of this event"
                android:textColor="#aaa"
                android:textSize="16sp" />
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

但问题是我写了一些代码，但我不知道为什么在调试我的应用程序后，我看到的唯一一件事就是事件的名称。

以下是代码：

public class Event extends LinearLayout{

    private LinearLayout globalContener;
    private LinearLayout contener;
    private LinearLayout avatarBox;
    private LinearLayout contentBox;

    private TextView eventName;
    private TextView eventGroup;

    private ImageView avatar;

    private LinearLayout.LayoutParams globalContenerParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    private LinearLayout.LayoutParams contenerParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    private LinearLayout.LayoutParams avatarBoxParams = new LinearLayout.LayoutParams(160, LayoutParams.MATCH_PARENT, 1.0f);
    private LinearLayout.LayoutParams contentBoxParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

    private LinearLayout.LayoutParams eventNameParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    private LinearLayout.LayoutParams eventGroupParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

    private LinearLayout.LayoutParams avatarParams = new LinearLayout.LayoutParams(48, 48);

    public Event(Context context){
        super(context);

        // Design of global contener
        globalContenerParams.setMargins(0, 0, 0, 32);

        globalContener = new LinearLayout(context);
        globalContener.setBackgroundColor(0xDDDDDD);
        globalContener.setPadding(1, 1, 1, 1);
        globalContener.setOrientation(LinearLayout.VERTICAL);
        globalContener.setLayoutParams(globalContenerParams);

        // Design of contener
        contener = new LinearLayout(context);
        contener.setBackgroundColor(0xFFFFFF);
        contener.setPadding(0, 26, 0, 26);
        contener.setOrientation(LinearLayout.HORIZONTAL);
        contener.setLayoutParams(contenerParams);

        // Design of avatar box
        avatarBox = new LinearLayout(context);
        avatarBox.setBackgroundColor(0xFFFFFF);
        avatarBox.setLayoutParams(avatarBoxParams);

        // Design of contet box
        contentBox = new LinearLayout(context);
        contentBox.setOrientation(LinearLayout.VERTICAL);
        contentBox.setBackgroundColor(0xFFFFFF);
        contentBox.setLayoutParams(contentBoxParams);

        // Design of avatar
        avatarParams.gravity = Gravity.TOP;
        avatarParams.setMargins(32, 4, 0, 0);

        avatar = new ImageView(context);
        avatar.setBackgroundDrawable(Const.avatarImg);
        avatar.setLayoutParams(avatarParams);

        // Design of event name
        eventNameParams.gravity = Gravity.TOP;

        eventName = new TextView(context);
        eventName.setGravity(Gravity.TOP);
        eventName.setPadding(16, 0, 0, 4);
        eventName.setTextSize(22);
        eventName.setText("Sprawdzian z języka polskiego");
        eventName.setLayoutParams(eventNameParams);

        // Design of event group
        eventGroup = new TextView(context);
        eventGroup.setGravity(Gravity.CENTER);
        eventGroup.setPadding(16, 0, 0, 0);
        eventGroup.setTextSize(16);
        eventGroup.setTextColor(0xAAAAAA);
        eventGroup.setText("4ia Technikum Łączności w Krakowie");
        eventGroup.setLayoutParams(eventGroupParams);

        // Packing boxes
        avatarBox.addView(avatar);

        contentBox.addView(eventGroup);
        contentBox.addView(eventName);

        contener.addView(avatarBox);
        contener.addView(contentBox);

        globalContener.addView(contener);

        // Adding to view
        addView(globalContener);
    }
}

有谁在这里可以帮助我吗？

Answer 1

将主要LinearLayout方向设置为垂直然后
将contentBoxParams权重设置为1f

private LinearLayout.LayoutParams contentBoxParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,1.0f);

然后把这个

contentBox.addView(eventName);

之前

contentBox.addView(eventGroup);

然后替换所有 0xFFFFFF与0xFFFFFFFF
