Android的AlertDialog带有圆角 [英] Android AlertDialog with rounded corners
问题描述
我一直在试图让我的警告对话框带圆角的，但不知何故，我不能。我曾经试过，我失败了。我试图按照此博客 http://blog.stylingandroid.com/archives/271 ，使我的风格的基础上
I have been trying to make my Alert Dialog with rounded corners but somehow I am not able to. I have tried and I failed. I tried to follow this blog http://blog.stylingandroid.com/archives/271 and made my styles based on that.
顺便说一句，添加到我现在的问题。我的一些新发现的。在code在上面的链接只是正常工作的2.3.3（GB），但不会在ICS在所有的工作。一些变化作出的code打破。
我想避免造成9片图像，因此我使用的形状。 9片图像的是，我会try.I知道Android警告对话框风格采用9片图像的最后一件事。我已经看了，截至抛出这个问题之前。

ContextThemeWrapper ctw = new ContextThemeWrapper(context,

TextView text = (TextView)layout.findViewById(com.gp4ever.worldlogo.quiz.R.id.textView1);
Button buttonOk = (Button)layout.findViewById(com.gp4ever.worldlogo.quiz.R.id.button1);
Button buttonMore = (Button)layout.findViewById(com.gp4ever.worldlogo.quiz.R.id.button2);
text.setText(message);
if (messagedrawable > 0) {
text.setCompoundDrawablesWithIntrinsicBounds(messagedrawable, 0, 0, 0);
} else if (messagedrawable == 0)
text.setCompoundDrawablesWithIntrinsicBounds(0, 0, 0, 0);
builder.setView(layout);
builder.setCancelable(false);
builder.setTitle(headermessage);
builder.setIcon(android.R.drawable.ic_dialog_alert);
final AlertDialog dialog = builder.create();
buttonOk.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
buttonMore.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
}
我的电流输出：
我没有得到任何圆角。我可以看到它是一贯的风格不同。即使我改变半径在我的绘制，边角并不反映这些变化。
I do not get any rounded corners. I can see that it is different from the usual style. Even though I change radius on my drawable, the corners does not reflect to those changes.
推荐答案
您可以使用下面的code做到这一点：
You can do it using the following code:
CustomDialog.java：
CustomDialog.java:
public class MainActivity extends Activity{
private static final int ALERT_DIALOG = 1;
@Override
public void onCreate( Bundle savedInstanceState )
{
super.onCreate( savedInstanceState );
setContentView( R.layout.main );
( (Button) findViewById( R.id.button1 ) )
.setOnClickListener( new OnClickListener()
{
public void onClick( View v )
{
showDialog( ALERT_DIALOG );
}
}
);
}
@Override
protected Dialog onCreateDialog( int id ){
Dialog dialog = null;
if ( id == ALERT_DIALOG )
{
ContextThemeWrapper ctw = new ContextThemeWrapper( this, R.style.MyTheme );
AlertDialog.Builder builder = new AlertDialog.Builder( ctw );
builder.setMessage( "Hello World" )
.setTitle( "Alert Dialog" )
.setIcon( android.R.drawable.ic_dialog_alert )
.setCancelable( false )
.setPositiveButton( "Close", new DialogInterface.OnClickListener()
{
public void onClick( DialogInterface dialog, int which )
{
dialog.dismiss();
}
}
);
dialog = builder.create();
}
if ( dialog == null )
{
dialog = super.onCreateDialog( id );
}
return dialog;
}
}
dialog_title.xml
dialog_title.xml
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android" android:insetBottom="-1dp">
<shape android:shape="rectangle">
<solid android:color="#000000" />
<corners android:topLeftRadius="20dp" android:topRightRadius="20dp" />
<stroke android:color="#7F7F7F" android:width="1dp" />
</shape>
</inset>
dialog_footer.xml
dialog_footer.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#7F7F7F" />
<corners android:bottomLeftRadius="20dp" android:bottomRightRadius="20dp" />
<stroke android:color="#7F7F7F" android:width="1dp" />
</shape>
只要改变半径量：
Just change the radius amount in:
dialog_title.xml
和
dialog_footer.xml
那会生成以下的输出：
希望这会帮助你。
更新：
我不是专家，但是这是我发现。这可能是对还是错。
多次尝试后，我结束了以下内容：
UPDATE:
I'm not an expert but this is what I found. It may be right or wrong.
After many attempts I ended up with the following:
1 ContextThemeWrapper 不适用于14 API，它工作正常，在姜饼及以上版本，但与API> 10这是行不通的。
1- ContextThemeWrapper is not applicable for API 14, it works fine on Gingerbread and older versions but with API > 10 it doesn't work.
2至克服上述问题，并在其API工作> 10的要求，我替换这行：
2- to overcome the above issue and make it work on API > 10 as requested, I replace this line:
ContextThemeWrapper ctw = new ContextThemeWrapper( this, R.style.MyTheme );
AlertDialog.Builder builder= new AlertDialog.Builder( ctw );
这一点：
AlertDialog.Builder builder= new AlertDialog.Builder( this,R.style.MyTheme );
但你需要改变：
but you need to change:
android:minSdkVersion="8"
到
android:minSdkVersion="11"
的结果将在下面的图像上的ICS（API 14）所示：
the result will be as shown in the following image on ICS (API 14):
该图像是从三星Galaxy S3运行ICS。
This image is from a Samsung Galaxy S3 running ICS.
请注意：修改与API 14 SO清单SDK发起的项目将是：
Note: modified project initiated with API 14 SO manifest sdk will be:
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="15" />
一锤定音： 正如我在Android开发小知识（我不是专家），
FINAL WORD: As my little knowledge in Android development (I'm not an expert),
1 - 自定义警告对话框顺利运行的API＆LT; 10但不是10用同样的Java code，
1- custom alert dialog runs smoothly in API < 10 but not > 10 with the same Java code,
如果我们希望它在ICS具有相同的效果出现在API＆LT运行; 10，我们需要修改code ，所以它可以运行在ICS，但不会在任何版本的办下来API 11。
if we want it to run in ICS with the same effect as appeared in API < 10, we need to modify the code, so it will run on ICS but will not run in any version down API 11.
2 - 甚至导致ICS不尽如人意，圆角仅适用于标题，但没有页脚。
2- even the result in ICS is not satisfactory, the round corner applies only to the title but not the footer.
第二次更新： 最后，我得到各个角落全面，
SECOND UPDATE: FINALLY I get all corners round,
JUST适用填充到 dialog_footer.xml 如下：
JUST apply padding to dialog_footer.xml as follows:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#7F7F7F" />
<corners android:bottomLeftRadius="20dp" android:bottomRightRadius="20dp" />
<stroke android:color="#7F7F7F" android:width="1dp" />
<padding android:left="10dp" android:top="10dp" android:right="10dp"
android:bottom="10dp" />
</shape>
输出图像：
此图片是从三星Galaxy S3运行ICS。
