android 对话框总结
1、AlertDialog对话框
AlertDialog.Builder builder=new Builder(HomeActivity.this);
builder.setTitle("提示");
builder.setMessage("是否删除信息?");
builder.setPositiveButton("是",new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
new AsyncTask<Void, Void, Void>(){
@Override
protected Void doInBackground(Void... params) {
//同意则把当前数据写入请假申请表里
if(mRejectLeaveInfoDao==null){
mRejectLeaveInfoDao=new RejectLeaveInfosDao(HomeActivity.this);
}else{
mRejectLeaveInfoDao.deleteLeaveInfo(tmpInfoReject);
}
fillDataReject();
return null;
}
}.execute();
}
});
builder.setNegativeButton("否",new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builder.create().show();
}2、Dialog对话框
new AsyncTask<Void,Object, Void>() {
List<VirusApp> apps=new ArrayList<VirusApp>();
String desc=null;
Dialog dialog=new Dialog(KillVirusActivity.this);
View viewKilling=View.inflate(KillVirusActivity.this,R.layout.killing_dialog,null);
@Override
protected void onPreExecute() {
mKillVirusResult.setText("正在扫描中，请稍等...");
dialog.setCancelable(false);
dialog.setContentView(viewKilling);
dialog.show();对应布局文件：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

public AddKeyWordsInfosDailogActivity() {
}
@Override

//去除title
requestWindowFeature(Window.FEATURE_NO_TITLE);
//去掉Activity上面的状态栏
getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN , WindowManager.LayoutParams. FLAG_FULLSCREEN);
setContentView(R.layout.add_keyword_info_activity);
init();
setListener();
}
private void setListener() {
mSure.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
KeyWordInfoDao dao=new KeyWordInfoDao(getApplicationContext());
if(et_key_words_input.getText().toString().trim().length()==0){
Toast.makeText(AddKeyWordsInfosDailogActivity.this,"请输入关键字或者取消！",300).show();
return;
}
if(et_key_words_decribe.getText().toString().trim().length()==0){
Toast.makeText(AddKeyWordsInfosDailogActivity.this,"请输入关键字描述内容或者取消！",300).show();
return;
}
KeyWordInfo info=new KeyWordInfo();
info.setKey_word_info(et_key_words_input.getText().toString().trim());

//把拦截关键字加入数据库
dao.addKeyWordInfos(info);
info=null;
setResult(ADD_KEY_INFO_SCUCESS, getIntent());
AddKeyWordsInfosDailogActivity.this.finish();
}
});
mCancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
AddKeyWordsInfosDailogActivity.this.finish();
}
});
}
private void init() {
et_key_words_input=(EditText) findViewById(R.id.et_key_words_input);
et_key_words_decribe=(EditText) findViewById(R.id.et_key_words_decribe);
mSure=(Button) findViewById(R.id.btn_sure);
mCancel=(Button) findViewById(R.id.btn_cancel);
}
@Override
protected void onDestroy() {
super.onDestroy();
}
}
