• Android-ViewPagerIndicator框架使用——LinePageIndicator


    前言:LinePageIndicator类似CirclePageIndicator,只是将圆点指示变成了长条指示。

        一:使用是定义的布局文件simple_lines  :

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >
    
        <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"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:padding="5dip" />
    </LinearLayout>

        二:代码中使用:

            setContentView(R.layout.simple_lines);
    
            mAdapter = new TestFragmentAdapter(getSupportFragmentManager());
    
            ViewPager mPager = (ViewPager) findViewById(R.id.pager);
            mPager.setAdapter(mAdapter);
    
            LinePageIndicator mIndicator = (LinePageIndicator) findViewById(R.id.indicator);
            mIndicator.setViewPager(mPager);

        三:修改属该改变样式,下边可以修改的属性值:

    <declare-styleable name="LinePageIndicator">
    
            <!-- 是否居中显示 -->
            <attr name="centered" />
            <!-- 没有被选择标识的颜色 -->
            <attr name="unselectedColor" />
            <!-- 被选择标识的颜色 -->
            <attr name="selectedColor" />
            <!-- 标识的宽度大小 -->
            <attr name="lineWidth" format="dimension" />
            <!-- 标识的高度 -->
            <attr name="strokeWidth" />
            <!-- 标识间隔大小 -->
            <attr name="gapWidth" format="dimension" />
            <!-- 整体的背景色 -->
            <attr name="android:background" />
        </declare-styleable>

          1.代码修改样式:

    @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.simple_lines);
    
            mAdapter = new TestFragmentAdapter(getSupportFragmentManager());
    
            mPager = (ViewPager) findViewById(R.id.pager);
            mPager.setAdapter(mAdapter);
    
            LinePageIndicator indicator = (LinePageIndicator) findViewById(R.id.indicator);
            mIndicator = indicator;
            indicator.setViewPager(mPager);
            // 获得屏幕的密度
            final float density = getResources().getDisplayMetrics().density;
            indicator.setSelectedColor(0x88FF0000);
            indicator.setUnselectedColor(0xFF888888);
            indicator.setStrokeWidth(4 * density);
            indicator.setLineWidth(30 * density);
        }

          2.布局中修改:

    <LinearLayout 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:orientation="vertical" >
    
        <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"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:padding="5dip"
            app:lineWidth="30dp"
            app:selectedColor="#FF880000"
            app:strokeWidth="4dp"
            app:unselectedColor="#FF888888" />
    </LinearLayout>

          3.主题方式修改:

            <activity
                android:name=".SampleLinesStyledTheme"
                android:label="Lines/Styled (via theme)"
                android:theme="@style/CustomLinePageIndicator" >
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
    
                    <category android:name="com.jakewharton.android.viewpagerindicator.sample.SAMPLE" />
                </intent-filter>
            </activity>

          主题:

        <style name="CustomLinePageIndicator" parent="@android:style/Theme.Light">
            <item name="strokeWidth">4dp</item>
            <item name="lineWidth">30dp</item>
            <item name="unselectedColor">#FF888888</item>
            <item name="selectedColor">#FF880000</item>
        </style>
