ListView的侧滑删除原来如此简单

基本思路：item的跟布局用HorizontalScrollView，然后把除删除外的布局宽度在代码中设置成屏幕宽度

activity_test.xml

<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="@dimen/title_height"
        android:gravity="center_vertical"
        android:orientation="horizontal">
        <RelativeLayout
            android:id="@+id/rl1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
            <TextView
                android:id="@+id/tv"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:textSize="18sp"
                android:text="这是填充全屏宽的"/>
            <TextView
                android:id="@+id/tv2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:textSize="18sp"
                android:text="末尾"/>
        </RelativeLayout>

        <Button
            android:id="@+id/btn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="删除"
            android:padding="@dimen/x5"/>
    </LinearLayout>

</HorizontalScrollView>

代码里这么弄：

RelativeLayout rl1 = (RelativeLayout) findViewById(R.id.rl1);
        Button btn = (Button) findViewById(R.id.btn);
        ViewGroup.LayoutParams lp = rl1.getLayoutParams();
        lp.width = DensityUtil.getDeviceInfo(this)[0];
        rl1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                ToastUtils.showToast("点击了整条");
            }
        });
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                ToastUtils.showToast("点击了删除");
            }
        });

public class DensityUtil {


    private static int[] deviceWidthHeight = new int[2];

    public static int[] getDeviceInfo(Context context) {

        if ((deviceWidthHeight[0] == 0) && (deviceWidthHeight[1] == 0)) {

            DisplayMetrics metrics = new DisplayMetrics();

            ((Activity) context).getWindowManager().getDefaultDisplay()

                    .getMetrics(metrics);


            deviceWidthHeight[0] = metrics.widthPixels;

            deviceWidthHeight[1] = metrics.heightPixels;

        }

        return deviceWidthHeight;

    }
}
