文字就不說了，直接上代碼。
1.三個選項Dialog.
效果圖如下：
/**
* 三個選項的Dialog
*/
private void threeDialog(){
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("帶進度條的Dialog");
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "確定", Toast.LENGTH_SHORT).show();
}
});
builder.setNeutralButton("中間", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "中間", Toast.LENGTH_SHORT).show();
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "取消", Toast.LENGTH_SHORT).show();
}
});
builder.create().show();
}
二、進度條Dialog。
代碼：
/**
* 進度條Dialog
*/
private void progressDialog(){
mProgress = new ProgressDialog(mContext);
mProgress.setIcon(R.drawable.ic_launcher);
mProgress.setTitle("帶進度條的Ｄialog");
mProgress.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgress.setButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "確定", Toast.LENGTH_SHORT).show();
}
});
mProgress.setButton2("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "取消", Toast.LENGTH_SHORT).show();
}
});
mProgress.show();
new Thread(new Runnable() {
int progress = 0;
@Override
public void run() {
// TODO Auto-generated method stub
while (progress <= 100) {
mProgress.setProgress(progress);
try {
Thread.sleep(100);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
progress++;
}
}
}).start();
}
三、單選Dialog
/**
* 單選Dialog
*/
private void simpleDialog(){
singleSelectedId = -1;
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("單選Dialog");
builder.setSingleChoiceItems(items, 0, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
singleSelectedId = which;
Toast.makeText(mContext, "你選擇的ID爲："+which, Toast.LENGTH_SHORT).show();
}
});
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
if (singleSelectedId >= 0) {
Toast.makeText(mContext, "你選擇的ID爲："+singleSelectedId, Toast.LENGTH_SHORT).show();
} else {
singleSelectedId = 0;
// 業務邏輯
}
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
});
builder.create().show();
}
四、多選複選Dialog
/**
* 複選Dialog
*/
private void chooseDialog(){
boolean[] selected = new boolean[items.length];
for (int i = 0; i < selected.length; i++) {
selected[i] = false;
}
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("複選Dialog");
builder.setMultiChoiceItems(items, selected, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
// TODO Auto-generated method stub
if (isChecked) {
list.add(which);
} else {
list.remove(which);
}
}
});
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
String str = "你選擇了：";
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
for (int i = 0; i < list.size(); i++) {
str += " "+items[list.get(i)];
}
Toast.makeText(mContext, str, Toast.LENGTH_LONG).show();
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
});
builder.create().show();
}
五、自定義Dialog
/**
* 自定義Dialog
*/
EditText username;
EditText password;
private void customDialog(){
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
LayoutInflater flater = LayoutInflater.from(mContext);
final View view = flater.inflate(R.layout.login, null);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("自定義Dialog");
builder.setView(view);
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
username = (EditText) view.findViewById(R.id.username);
password = (EditText) view.findViewById(R.id.pwd);
Toast.makeText(mContext, ""+username.getText()+password.getText(), Toast.LENGTH_LONG).show();
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
});
builder.create().show();
}
整體代碼如下：

private ArrayList<Integer> list;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mContext = HelloDialogActivity.this;
prepare();
}
private void prepare(){

btnThree.setOnClickListener(this);
btnProgress.setOnClickListener(this);
btnSingle.setOnClickListener(this);
btnChoices.setOnClickListener(this);
btnCustom.setOnClickListener(this);
}
