应用程序无法在API 21中运行

Question

I have an application which has a gridview with images in it. The problem is its showing in all phones except for API 21 ie Lollipop version. In Lollipop its shows just background and no gridview. The targetSDK is 21 and minSDK is 8. Any help in this would be much appreciated.

 MainActivity public class MainView extends Activity { ImageView back, home, site, header; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setTheme(android.R.style.Theme_Translucent_NoTitleBar_Fullscreen); getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WALLPAPER); setContentView(R.layout.mainview); GridView gridView = (GridView)findViewById(R.id.gridview); gridView.setAdapter(new MyAdapter(this)); gridView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View v, int position, long id) { Intent myIntent = null; if(position == 0){ myIntent = new Intent(v.getContext(), TheShow.class); } if(position == 1){ myIntent = new Intent(v.getContext(), Exhibitor.class); } if(position ==2){ myIntent = new Intent(v.getContext(), Visitor.class); } if(position ==3){ myIntent = new Intent(v.getContext(), Conference.class); } if(position ==4){ myIntent = new Intent(v.getContext(), ContactUs.class); } if(position == 5){ myIntent = new Intent(v.getContext(), ExhibitorReg.class); } if(position == 6){ myIntent = new Intent(v.getContext(), VisitorReg.class); } if(position == 7){ myIntent = new Intent(v.getContext(), FlrPlan.class); } if(myIntent!=null){ startActivity(myIntent); } } }); back=(ImageView)findViewById(R.id.imageView2); home=(ImageView)findViewById(R.id.imageView3); site=(ImageView)findViewById(R.id.imageView4); back.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub MainView.this.onBackPressed(); } }); home.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Toast.makeText(getApplicationContext(), "Same Page", Toast.LENGTH_LONG).show(); } }); site.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub String url = "http://india-aviation.in/"; Intent i = new Intent(Intent.ACTION_VIEW); i.setData(Uri.parse(url)); startActivity(i); } }); header=(ImageView)findViewById(R.id.imageView1); header.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub final Dialog dialog = new Dialog(MainView.this); dialog.setContentView(R.layout.custom_dialog); dialog.setTitle("About Us"); dialog.setCancelable(true); Button button = (Button) dialog.findViewById(R.id.buttonOK); button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); dialog.show(); } }); } private class MyAdapter extends BaseAdapter { private List<Item> items = new ArrayList<Item>(); private LayoutInflater inflater; public MyAdapter(Context context) { inflater = LayoutInflater.from(context); items.add(new Item("The Show", R.drawable.globecopy1)); items.add(new Item("Exhibitor", R.drawable.workcopy1)); items.add(new Item("Visitor", R.drawable.visitor1copy1)); items.add(new Item("Conference", R.drawable.conferencecopy1)); items.add(new Item("Contact Us", R.drawable.contactus1copy1)); items.add(new Item("Exhibitor Registration", R.drawable.exregistercopy1)); items.add(new Item("Visitor Registration", R.drawable.anothercopy1)); items.add(new Item("Layout Plan", R.drawable.registercopy1)); } @Override public int getCount() { return items.size(); } @Override public Object getItem(int i) { return items.get(i); } @Override public long getItemId(int i) { return items.get(i).drawableId; } @Override public View getView(int i, View view, ViewGroup viewGroup) { View v = view; ImageView picture; TextView name; if(v == null) { v = inflater.inflate(R.layout.gridview_item, viewGroup, false); v.setTag(R.id.picture, v.findViewById(R.id.picture)); v.setTag(R.id.text, v.findViewById(R.id.text)); } picture = (ImageView)v.getTag(R.id.picture); name = (TextView)v.getTag(R.id.text); Item item = (Item)getItem(i); picture.setImageResource(item.drawableId); name.setText(item.name); return v; } private class Item { final String name; final int drawableId; Item(String name, int drawableId) { this.name = name; this.drawableId = drawableId; } } } }

如果您的应用程序在res文件夹中有一个values-21文件夹，请在该位置设置布局，或者如果要为所有API设置永久布局，请删除该文件夹。
