Question

此链接将为viewpager指示器内衬样式提供图像。

我的问题是如何摆脱默认的白色背景并将其透明化？

例如，看起来像这样：http://24.media.tumblr.com/d0816263966dcb14f4b6a655f1f6bbc0/tumblr_mwzn1tKAAU1r2wjwko1_1280.png

顺便说一下，这是我的代码。

主题行代码布局：

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

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        />

    <com.viewpagerindicator.LinePageIndicator
        android:id="@+id/indicator"
        style="@style/CustomLinePageIndicator"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0.04"
        android:padding="5dip"
        app:lineWidth="30dp"
        app:selectedColor="#FF24248F"
        app:strokeWidth="4dp"
        app:unselectedColor="#FF8FB28F"
         />

</LinearLayout>

主要活动代码：

import com.viewpagerindicator.PageIndicator;
import com.viewpagerindicator.LinePageIndicator;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.Menu;
import co.sav.prime.R;

public class MainActivity extends FragmentActivity {

    FragmentAdapter mAdapter;
    ViewPager mPager;
    PageIndicator mIndicator;
    int Number = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.themed_lines);

        mAdapter = new FragmentAdapter(getSupportFragmentManager());

        mPager = (ViewPager)findViewById(R.id.pager);
        mPager.setAdapter(mAdapter);

        mIndicator = (LinePageIndicator)findViewById(R.id.indicator);
        mIndicator.setViewPager(mPager);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

Answer 1

我想我得到了。您正在使用LinearLayout，您的ViewPager位于PagerIndicator上方，因此白色是视图的背景颜色。你可以使用RelativeLayout解决这个问题，然后输入：

android:layout_alignParentBottom="true"

在你的PagerIndicator中

。

尝试这样的事情：

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        />

    <com.viewpagerindicator.LinePageIndicator
        android:id="@+id/indicator"
        style="@style/CustomLinePageIndicator"
        android:layout_width="fill_parent"
        android:layout_height="10dp"
        android:layout_alignParentBottom="true"
        android:padding="5dip"
        app:lineWidth="30dp"
        app:selectedColor="#FF24248F"
        app:strokeWidth="4dp"
        app:unselectedColor="#FF8FB28F"
         />

</RelativeLayout>

ViewPager初始背景？
