最近做的launcher项目里一个显示对话框效果。好多朋友都问我要代码,所以今天抽了点时间把这段代码扣出来,分享给大家《

代码相对较多些,我就不一一阐述。项目里抠出来的,一些没必要的也都在里边了。使用作法如下
public class MainActivity extends Activity implements OnCorpusSelectedListener { public CorpusSelectionDialog mCorpusSelectionDialog; private List<Corpus> mAppCategoryList; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initData(); Button b = (Button) this.findViewById(R.id.button1); b.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { showCorpusSelectionDialog(); } }); } @Override public void onCorpusSelected(Corpus corpus) { Toast.makeText(this, corpus.label + "被点了", Toast.LENGTH_LONG).show(); } /** * 显示自定义dialog */ protected void showCorpusSelectionDialog() { if (mCorpusSelectionDialog == null) { mCorpusSelectionDialog = new CategoryAppDialog(this, mAppCategoryList); mCorpusSelectionDialog.setOwnerActivity(this); mCorpusSelectionDialog.setOnCorpusSelectedListener(this); } mCorpusSelectionDialog.show(); }
