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《转帖的朋友，请标明出处，尊重作者的劳动成果》。上图吧
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();
}
