andrdroid基礎---對話方塊：Dialog、AlertDialog
1.確定取消對話方塊
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);
builder.setIcon(R.drawable.icon);
builder.setTitle("你確定要離開嗎？");
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//這裡新增點選確定後的邏輯
showDialog("你選擇了確定");
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//這裡新增點選確定後的邏輯
showDialog("你選擇了取消");
}
});
builder.create().show();
private void showDialog
new AlertDialog.Builder(MainDialog.this).setMessage(str).show();
}
----------------------------------------------------------------------------------------------------------
2.多個按鈕資訊框
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);
builder.setIcon(R.drawable.icon);
builder.setTitle("投票");
builder.setMessage("您認為什麼樣的內容能吸引您？");
builder.setPositiveButton("有趣味的", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
showDialog("你選擇了有趣味的");
}
});
builder.setNeutralButton("有思想的", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
showDialog("你選擇了有思想的");
}
});
builder.setNegativeButton("主題強的", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
showDialog("你選擇了主題強的");
}
});
builder.create().show();
3.列表框
final String[] mItems = {"item0","item1","itme2","item3","itme4","item5","item6"};
[java] view plaincopy
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);
builder.setTitle("列表選擇框");
builder.setItems(mItems, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//點選後彈出視窗選擇了第幾項
showDialog("你選擇的id為" + which + " , " + mItems[which]);
}
});
builder.create().show();
4.單項選擇列表框
int mSingleChoiceID = -1;
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);
mSingleChoiceID = -1;
builder.setIcon(R.drawable.icon);
builder.setTitle("單項選擇");
builder.setSingleChoiceItems(mItems, 0, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
mSingleChoiceID = whichButton;
showDialog("你選擇的id為" + whichButton + " , " + mItems[whichButton]);
}
});
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
if(mSingleChoiceID > 0) {
showDialog("你選擇的是" + mSingleChoiceID);
}
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
builder.create().show();
5.進度條框
mProgressDialog = new ProgressDialog(MainDialog.this);
mProgressDialog.setIcon(R.drawable.icon);
mProgressDialog.setTitle("進度條視窗");
mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setMax(MAX_PROGRESS);
mProgressDialog.setButton("確定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//這裡新增點選後的邏輯
}
});
mProgressDialog.setButton2("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
//這裡新增點選後的邏輯
}
});
mProgressDialog.show();
new Thread(this).start();
public void run() {
int Progress = 0;
while(Progress < MAX_PROGRESS) {
try {
Thread.sleep(100);
Progress++;
mProgressDialog.incrementProgressBy(1);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
6.多項選擇列表框
ArrayListMultiChoiceID = new ArrayList();
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this);
MultiChoiceID.clear();
builder.setIcon(R.drawable.icon);
builder.setTitle("多項選擇");
builder.setMultiChoiceItems(mItems,
new boolean[]{false, false, false, false, false, false, false},
new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int whichButton,boolean isChecked) {
if(isChecked) {
MultiChoiceID.add(whichButton);
showDialog("你選擇的id為" + whichButton + " , " + mItems[whichButton]);
}else {
MultiChoiceID.remove(whichButton);
}
}
});
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String str = "";
int size = MultiChoiceID.size();
for (int i = 0 ;i < size; i++) {
str+= mItems[MultiChoiceID.get(i)] + ", ";
}
showDialog("你選擇的是" + str);
}
});
builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
builder.create().show();
7.自定義佈局
|
2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
AlertDialog.Builder builder = new AlertDialog.Builder(MainDialog.this); LayoutInflater factory = LayoutInflater.from(this); final View textEntryView = factory.inflate(R.layout.test, null); builder.setIcon(R.drawable.icon); builder.setTitle("自定義輸入框"); builder.setView(textEntryView); builder.setPositiveButton("確定", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { EditText userName = (EditText) textEntryView.findViewById(R.id.etUserName); EditText password = (EditText) textEntryView.findViewById(R.id.etPassWord); showDialog("姓名 ：" + userName.getText().toString() + "密碼：" + password.getText().toString() ); } }); builder.setNegativeButton("取消", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { } }); builder.create().show(); |
8.讀取進度框
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setTitle("讀取ing");
mProgressDialog.setMessage("正在讀取中請稍候");
mProgressDialog.setIndeterminate(true);
mProgressDialog.setCancelable(true);
mProgressDialog.show();
