173 // instantiate the dialog with the custom Theme 174 final CustomDialog dialog = new CustomDialog(context, 175 R.style.mystyle); 176 View layout = inflater.inflate(R.layout.customdialog, null); 177 dialog.addContentView(layout, new LayoutParams( 178 LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); 179 // set the dialog title 180 ((TextView) layout.findViewById(R.id.title)).setText(title); 181 ((TextView) layout.findViewById(R.id.title)).getPaint() 182 .setFakeBoldText(true); 183 184 if (title == null || title.trim().length() == 0) { 185 ((TextView) layout.findViewById(R.id.message)) 186 .setGravity(Gravity.CENTER); 187 } 188 189 if (neutral_btnText != null && confirm_btnText != null 190 && cancel_btnText != null) { 191 ((Button) layout.findViewById(R.id.confirm_btn)) 192 .setText(confirm_btnText); 193 if (neutral_btnClickListener != null) { 194 ((Button) layout.findViewById(R.id.neutral_btn)) 195 .setOnClickListener(new View.OnClickListener() { 196 public void onClick(View v) { 197 neutral_btnClickListener.onClick(dialog, 198 DialogInterface.BUTTON_NEUTRAL); 199 } 200 }); 201 } else { 202 ((Button) layout.findViewById(R.id.neutral_btn)) 203 .setOnClickListener(new View.OnClickListener() { 204 205 @Override 206 public void onClick(View v) { 207 dialog.dismiss(); 208 } 209 }); 210 } 211 } else { 212 // if no confirm button or cancle button or neutral just set the 213 // visibility to GONE 214 layout.findViewById(R.id.neutral_btn).setVisibility(View.GONE); 215 layout.findViewById(R.id.single_line).setVisibility(View.GONE); 216 } 217 // set the confirm button 218 if (confirm_btnText != null) { 219 ((Button) layout.findViewById(R.id.confirm_btn)) 220 .setText(confirm_btnText); 221 if (confirm_btnClickListener != null) { 222 ((Button) layout.findViewById(R.id.confirm_btn)) 223 .setOnClickListener(new View.OnClickListener() { 224 public void onClick(View v) { 225 confirm_btnClickListener.onClick(dialog, 226 DialogInterface.BUTTON_POSITIVE); 227 } 228 }); 229 } else { 230 ((Button) layout.findViewById(R.id.confirm_btn)) 231 .setOnClickListener(new View.OnClickListener() { 232 233 @Override 234 public void onClick(View v) { 235 dialog.dismiss(); 236 } 237 }); 238 } 239 } else { 240 // if no confirm button just set the visibility to GONE 241 layout.findViewById(R.id.confirm_btn).setVisibility(View.GONE); 242 layout.findViewById(R.id.second_line).setVisibility(View.GONE); 243 layout.findViewById(R.id.cancel_btn).setBackgroundResource( 244 R.drawable.single_btn_select); 245 } 246 // set the cancel button 247 if (cancel_btnText != null) { 248 ((Button) layout.findViewById(R.id.cancel_btn)) 249 .setText(cancel_btnText); 250 if (cancel_btnClickListener != null) { 251 ((Button) layout.findViewById(R.id.cancel_btn)) 252 .setOnClickListener(new View.OnClickListener() { 253 public void onClick(View v) { 254 cancel_btnClickListener.onClick(dialog, 255 DialogInterface.BUTTON_NEGATIVE); 256 } 257 }); 258 } else { 259 ((Button) layout.findViewById(R.id.cancel_btn)) 260 .setOnClickListener(new View.OnClickListener() { 261 262 @Override 263 public void onClick(View v) { 264 dialog.dismiss(); 265 } 266 }); 267 } 268 } else { 269 // if no cancel button just set the visibility to GONE 270 layout.findViewById(R.id.cancel_btn).setVisibility(View.GONE); 271 layout.findViewById(R.id.second_line).setVisibility(View.GONE); 272 layout.findViewById(R.id.confirm_btn).setBackgroundResource( 273 R.drawable.single_btn_select); 274 } 275 // set the content message 276 if (message != null) { 277 ((TextView) layout.findViewById(R.id.message)).setText(message); 278 } else if (contentView != null) { 279 // if no message set 280 // add the contentView to the dialog body 281 ((LinearLayout) layout.findViewById(R.id.message)) 282 .removeAllViews(); 283 ((LinearLayout) layout.findViewById(R.id.message)).addView( 284 contentView, new LayoutParams( 285 LayoutParams.WRAP_CONTENT, 286 LayoutParams.WRAP_CONTENT)); 287 } 288 dialog.setContentView(layout); 289 return dialog; 290 } 291 292 } 293 }
2.CustomDialog的样式：
1 <style name="mystyle" parent="@android:style/Theme.Dialog"> 2 <item name="android:windowFrame">@null</item> 3 <item name="android:windowIsFloating">true</item> 4 <item name="android:windowIsTranslucent">false</item> 5 <item name="android:windowNoTitle">true</item> 6 <item name="android:windowBackground">@drawable/bg</item> 7 <item name="android:backgroundDimEnabled">true</item> 8 </style>
3.<item name="android:windowBackground">@drawable/bg</item> -> bg.xml
1 <?xml version="1.0" encoding="utf-8"?> 2 <shape xmlns:android="http://schemas.android.com/apk/res/android" > 3 4 <gradient 5 android:angle="90" 6 android:endColor="#ffffff" 7 android:startColor="#ffffff" /> 8 9 <solid android:color="#ffffff" /> 10 11 <corners 12 android:bottomLeftRadius="15px" 13 android:bottomRightRadius="15px" 14 android:topLeftRadius="15px" 15 android:topRightRadius="15px" /> 16 17 </shape>
4.在需要的地方调用即可：
1 private void backDialog() { 2 3 4 CustomDialog.Builder ibuilder = new CustomDialog.Builder(CommentDialogActivity.this); 5 ibuilder.setTitle("提示"); 6 ibuilder.setMessage("是否取消评论?"); 7 ibuilder.setPositiveButton("确定", new DialogInterface.OnClickListener() { 8 9 public void onClick(DialogInterface dialog, int which) { 10 dialog.dismiss(); 11 finish(); 12 overridePendingTransition(0, R.anim.roll_down); 13 } 14 }); 15 ibuilder.setNegativeButton("取消", new DialogInterface.OnClickListener() { 16 17 public void onClick(DialogInterface dialog, int which) { 18 dialog.cancel(); 19 } 20 }); 21 ibuilder.create().show(); 22 }
效果如图：
问题：
在使用过程中，当Activity设置为取消标题栏时，会出现CustomDialog变形的情况，如图：
真的很莫名其妙，后面逐一排除比对才找出该原因所在，具体原理不知，恳请知道的大牛评论告知，谢谢。
出现如上问题，是因为：
如下设置取消标题栏：
1 <activity 2 android:name=".CommentDialogActivity" 3 android:label="@string/title_activity_comment" 4 android:screenOrientation="portrait" 5 android:theme="@android:style/Theme.NoTitleBar" 6 android:windowSoftInputMode="adjustUnspecified|adjustResize" > 7 </activity>
而解决该问题，需要使用另一种方式来设置取消标题栏：
1 protected void onCreate(Bundle savedInstanceState) { 2 super.onCreate(savedInstanceState); 3 requestWindowFeature(Window.FEATURE_NO_TITLE);//去掉标题栏 4 setContentView(R.layout.dialog_sendcomments); 5 }
小伙伴们有兴趣可以试一下。
