Dialog的基本方法
//创建DialogAlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);//设置标题图标builder.setIcon(R.drawable.ic_launcher);//设置标题builder.setTitle("这是一个对话框");//设置信息builder.setMessage("是否要跳转？");//确定按钮setPositiveButton(CharSequence text, DialogInterface.OnClickListener listener)//取消按钮setNegativeButton (CharSequence text, DialogInterface.OnClickListener listener)//忽略setNeutralButton (CharSequence text, DialogInterface.OnClickListener listener)//显示对话框show();
系统样式
1.下拉列表
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); builder.setIcon(R.drawable.ic_launcher); builder.setTitle("选择一个城市"); //下拉列表的数据源 final String[] cities = {"北京", "上海", "广州", "深圳", "杭州"}; builder.setItems(cities, new DialogInterface.OnClickListener(){ @Override public void onClick(DialogInterface dialog, int which){ Toast.makeText(MainActivity.this, "你选择的城市为：" + cities[which], Toast.LENGTH_SHORT).show(); } }); builder.show();
2.单选框列表
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); builder.setIcon(R.drawable.ic_launcher); builder.setTitle("请选择性别"); final String[] sex = {"男", "女"}; //第二个参数指定默认哪个单选框被勾中 builder.setSingleChoiceItems(sex, 1, new DialogInterface.OnClickListener(){ @Override public void onClick(DialogInterface dialog, int which){ Toast.makeText(MainActivity.this, "性别为：" + sex[which], Toast.LENGTH_SHORT).show(); } }); builder.setPositiveButton("确定", new DialogInterface.OnClickListener(){ @Override public void onClick(DialogInterface dialog, int which){ } }); builder.setNegativeButton("取消", new DialogInterface.OnClickListener(){ @Override public void onClick(DialogInterface dialog, int which){ } });builder.show();
3.多选框列表
String str;AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);builder.setIcon(R.drawable.ic_launcher);builder.setTitle("选择你想看的电视剧");final String[] hobbies = {"廷禧攻略", "扶摇", "香蜜沉沉烬如霜", "如懿传"};//第二个参数代表哪几个选项被选择，需要传递一个boolean[]数组进去，其长度要和第一个参数的长度相同,如果null表示都不选builder.setMultiChoiceItems(hobbies, null, new DialogInterface.OnMultiChoiceClickListener(){ @Override public void onClick(DialogInterface dialog, int which, boolean isChecked){ if(isChecked){ str.append(hobbies[which] + ", "); } Toast.makeText(MainActivity.this, "选择的是：" + str.toString(), Toast.LENGTH_SHORT).show(); } });builder.setPositiveButton("确定", new DialogInterface.OnClickListener(){ @Override public void onClick(DialogInterface dialog, int which){ }});builder.setNegativeButton("取消", new DialogInterface.OnClickListener(){ @Override public void onClick(DialogInterface dialog, int which){ }});builder.show();
4.等待对话框
ProgressDialog waitingDialog= new ProgressDialog(MainActivity.this);waitingDialog.setTitle("等待加载中，请稍后...");waitingDialog.setMessage("等待中...");waitingDialog.setIndeterminate(true);//采用不确定式的进度条waitingDialog.setCancelable(false);//点击外部不取消对话框waitingDialog.show();
5.进度条对话框
int MAXPD = 100;ProgressDialog progressDialog = new ProgressDialog(MainActivity.this);progressDialog.setProgress(0);//设置默认值progressDialog.setTitle("正在下载");progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);//进度条样式progressDialog.setMax(MAXPD);//设置最大值progressDialog.show();
自定义Dialog
1.继承Dialog
public class CustomDialog extends Dialog {//标题protected TextView hintTv;//左边按钮protected Button doubleLeftBtn;//右边按钮protected Button doubleRightBtn;//输入框public EditText editText;public CustomDialog(Context context) { super(context, R.style.CustomDialogStyle);}@Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setCancelable(false); // 是否可以撤销 setContentView(R.layout.dialog_custom); hintTv = findViewById(R.id.tv_common_dialog_hint); doubleLeftBtn = findViewById(R.id.btn_common_dialog_double_left); doubleRightBtn = findViewById(R.id.btn_common_dialog_double_right); editText = findViewById(R.id.et_common_dialog);}//置右键文字和点击事件public void setRightButton(String rightStr, View.OnClickListener clickListener) { doubleRightBtn.setOnClickListener(clickListener); doubleRightBtn.setText(rightStr);}//设置左键文字和点击事件public void setLeftButton(String leftStr, View.OnClickListener clickListener) { doubleLeftBtn.setOnClickListener(clickListener); doubleLeftBtn.setText(leftStr);}//设置提示内容public void setHintText(String str) { hintTv.setText(str); hintTv.setVisibility(View.VISIBLE);}//给两个按钮 设置文字public void setBtnText(String leftStr, String rightStr) { doubleLeftBtn.setText(leftStr); doubleRightBtn.setText(rightStr);}}
2.自定义Style
<style name="CustomDialogStyle" parent="@android:style/Theme.Dialog"> <!-- 边框 --> <item name="android:windowFrame">@null</item> <!-- 背景透明 --> <item name="android:windowBackground">@color/transparent</item> <!-- 无标题 --> <item name="android:windowNoTitle">true</item> <!-- 是否浮现在activity之上 --> <item name="android:windowIsFloating">true</item> <!-- 半透明 --> <item name="android:windowIsTranslucent">false</item> <!-- 背景模糊 --> <item name="android:windowContentOverlay">@null</item> <!-- 允许对话框的背景变暗 --> <item name="android:backgroundDimEnabled">true</item> <!-- 字体颜色 --> <item name="android:textColor">@color/white</item> <item name="android:editTextColor">@color/white</item> </style>
3.自定义布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/ll_common_dialog_layout" android:layout_width="500dp" android:layout_height="250dp" android:layout_margin="5dp" android:background="@drawable/background_info" android:orientation="vertical" android:gravity="center"> <!--提示信息--> <TextView android:id="@+id/tv_common_dialog_hint" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:textColor="@color/white" android:textSize="27sp"/> <EditText android:id="@+id/et_common_dialog" android:layout_width="300dp" android:layout_height="wrap_content" android:textColor="@color/back" android:inputType="text|textNoSuggestions" tools:ignore="LabelFor" android:hint="请输入密码"/> <!--底部按钮--> <LinearLayout android:id="@+id/ll_common_dialog_double" android:layout_width="360dp" android:layout_height="60dp" android:layout_margin="20dp" android:orientation="horizontal"> <Button android:id="@+id/btn_common_dialog_double_left" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/btnselector" android:gravity="center" android:textColor="@color/white" android:textSize="27dp"/> <Button android:id="@+id/btn_common_dialog_double_right" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@drawable/btnselector" android:gravity="center" android:textColor="@color/white" android:textSize="27dp"/> </LinearLayout></LinearLayout>
4.ipad隐藏底部虚拟按键
//弹出dialog时隐藏底部虚拟按键dialog.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);dialog.getWindow().getDecorView().setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() { @Override public void onSystemUiVisibilityChange(int visibility) { int uiOptions =View.SYSTEM_UI_FLAG_HIDE_NAVIGATION; if (Build.VERSION.SDK_INT >= 19) { uiOptions |= 0x00001000; } else { uiOptions |= View.SYSTEM_UI_FLAG_LOW_PROFILE; } dialog.getWindow().getDecorView().setSystemUiVisibility(uiOptions); }});
5.使用自定义Dialog
CustomDialog dialog = new CustomDialog(this);dialog.setHintText("请输入密码");dialog.setLeftButton("取消", new View.OnClickListener() { @Override public void onClick(View v) { dialog.dismiss(); }});dialog.setRightButton("确定", new View.OnClickListener() { @Override public void onClick(View v) { }});dialog.show();
