Android常用如下七種對話框,基本涵蓋了大部分應用場景,所以有些時候沒必要自己去定義對話框,除非對話框的樣式不滿足UI的設計.常用七種對話框如下所示:
- 簡單對話框
- 簡單列表對話框
- 單選列表對話框
- 多選列表對話框
- 進度條對話框
- 編輯對話框
- 自定義對話框
1. 簡單對話框
private void showNormalDialog() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("簡單對話框")
.setIcon(R.mipmap.ic_launcher)
.setMessage("這是一個簡單對話框")
.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//定義自己想要做的操作
showText("確定");
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("取消");
}
});
builder.create().show();
}
2. 簡單列表對話框
private void showListDialog() {
final String[] items = new String[]{"上海", "北京", "湖南", "湖北", "海南"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("簡單列表對話框");
//由於message 和 items 都屬於彈出框的內容部分,兩者只能顯示一個, 所以千萬不要加這句，不然列表顯示不出來
// builder.setMessage("這是一個簡單的列表對話框");
builder.setIcon(R.mipmap.ic_launcher);
builder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText(items[which]);
}
});
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("確定");
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("取消");
}
});
builder.create().show();
}
3. 單選列表對話框
private void showSingleChoiceDialog() {
final String[] items = new String[]{"上海", "北京", "湖南", "湖北", "海南"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("簡單列表對話框");
//由於message 和 items 都屬於彈出框的內容部分,兩者只能顯示一個, 所以千萬不要加這句，不然列表顯示不出來
// builder.setMessage("這是一個簡單的列表對話框");
builder.setIcon(R.mipmap.ic_launcher);
builder.setSingleChoiceItems(items, 1, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText(items[which]);
}
});
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("確定");
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("取消");
}
});
builder.create().show();
}
4. 多選對話框.
private void showMultiChoiceDialog() {
final String[] items = new String[]{"上海", "北京", "湖南", "湖北", "海南"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("簡單列表對話框");
//由於message 和 items 都屬於彈出框的內容部分,兩者只能顯示一個, 所以千萬不要加這句，不然列表顯示不出來
// builder.setMessage("這是一個簡單的列表對話框");
builder.setIcon(R.mipmap.ic_launcher);
builder.setMultiChoiceItems(items, new boolean[]{false, false, false, false, false}, new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
showText(items[which]);
}
});
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("確定");
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
showText("取消");
}
});
builder.create().show();
}
5. 進度條對話框.
private void showProgressDialog() {
final ProgressDialog dialog = new ProgressDialog(this);
final int MAX_PROGRESS = 100;
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
dialog.setCancelable(true);
dialog.setCanceledOnTouchOutside(false);
dialog.setIcon(R.mipmap.ic_launcher);
dialog.setTitle("提示");
dialog.setMessage("這是一個進度條對話框");
dialog.setProgress(0);
//監聽取消時間
dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
showText("進度條結束");
}
});
dialog.show();
new Thread(new Runnable() {
@Override
public void run() {
int progress = 0;
while (progress < MAX_PROGRESS) {
try {
Thread.sleep(50);
} catch (InterruptedException e) {
e.printStackTrace();
}
progress++;
//非UI線程，可以處理DialogUI
dialog.setProgress(progress);
}
dialog.cancel();
}
}).start();
}
6. 編輯對話框,也屬於自定義對話框.
private void showEditDialog() {
final EditText editText = new EditText(this);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setIcon(R.mipmap.ic_launcher);
builder.setTitle("編輯對話框");
builder.setMessage("這是一個編輯對話框");
builder.setView(editText);
builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String input = editText.getText().toString();
showText(input);
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
builder.create().show();
}
7. 自定義對話框
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="299dip"
android:layout_height="match_parent"
android:background="@color/white"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:text="提示"

android:layout_height="40.0dip"
android:gravity="center_vertical"
android:paddingLeft="20.0dip"
android:textSize="16dip"
android:background="#288DF5"
android:textColor="@color/white"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dip"
android:gravity="left|center"
android:paddingLeft="20dip"
android:paddingRight="20dip"
android:textColor="@color/black"
android:text="@string/custom_dialog_msg"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dip">
<Button
android:layout_width="fill_parent"
android:layout_height="40dip"
android:layout_weight="1"
android:text="確定"
android:textColor="@color/white"
android:textSize="16sp"/>
<Button
android:layout_width="fill_parent"
android:layout_height="40dip"
android:layout_marginLeft="5dip"
android:layout_weight="1"
android:text="取消"
android:textColor="@color/white"
android:textSize="16sp"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
/**
* alertDialog提供了setView與setContentView兩種方法自定義視圖。
* setContentView是在AlertDialog的父類Dialog的方法，在父類Dialog方法中，是調用了Window.setContentView。這是對應整個對話框窗口的view。
* setView則是AlertDialog的方法,setView指的設置CustomView的部分而不是整個窗體,如果我們設置了buttonPanel又設置了contentPanel，則會在自定義的view下面顯示自帶的button。
