我想显示地方选择器,以便用户可以选择他/她自己选择的位置.但是地点选择器子活动在发布后会自动关闭.我已多次检查API密钥和其他权限,一切正确.这是所有代码.请帮忙!

task_location.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            try {
                PlacePicker.IntentBuilder intentBuilder = new PlacePicker.IntentBuilder();
                Intent intent = intentBuilder.build(NewTaskActivity.this);
                // Start the Intent by requesting a result, identified by a request code.
                startActivityForResult(intent, 123);


            } catch (GooglePlayServicesRepairableException e) {
                GooglePlayServicesUtil
                        .getErrorDialog(e.getConnectionStatusCode(), NewTaskActivity.this, 0);
            } catch (GooglePlayServicesNotAvailableException e) {
                Toast.makeText(NewTaskActivity.this, "Google Play Services is not available.",
                        Toast.LENGTH_LONG)
                        .show();
            }
        }
    });

我使用Recycler View作为我的listview和CardView作为列表项.当我点击列表中的任何项目时,我想扩展Cardview,就像它在Google/Gmail的收件箱应用中展开一样.请指导!

我正在使用回收器视图滑动来关闭，我的卡片视图或回收器项目包含水平滚动视图。每次触摸都会优先滑动以关闭。这是我的代码...请告诉如何将两次滑动分开？

我正在使用viewpager库来实现图像滑块，但不知道如何实现它来自动滚动。这是我的代码。

ViewPagerAdapter.java

public class ViewPagerAdapter extends FragmentPagerAdapter implements IconPagerAdapter{

private int[] Images = new int[] { R.drawable.viewpager, R.drawable.viewpager,
        R.drawable.viewpager, R.drawable.viewpager,R.drawable.viewpager, R.drawable.viewpager

};

protected static final int[] ICONS = new int[] { R.drawable.logo,
        R.drawable.logo, R.drawable.logo, R.drawable.logo,R.drawable.logo, R.drawable.logo };

private int mCount = Images.length;

public ViewPagerAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public Fragment getItem(int position) {
    return new SliderFragment(Images[position]);
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return mCount;
}

public int getIconResId(int index) {
    return ICONS[index % ICONS.length]; …

我想在地图片段上显示透明布局,其中包括一个图像和一个文本行作为地图上的提示.当用户点击该布局时,它将变为不可见,并且将显示地图.不知道在地图上显示透明的.请帮忙.
