但我收到一个异常java.lang.IllegalStateException:您需要在此活动中使用Theme.AppCompat主题(或子代)。
在此行final AlertDialog AlertDialog=builder.create()代码>
我的主要活动
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Toolbar toolbar =(Toolbar) findViewById(R.id.mainActivityBar);
setSupportActionBar(toolbar);
//other statements and methods here
}
My manifest.xml
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main"
android:theme="@style/mainActivityTheme">
</activity>
我的风格资源
<style name="mainActivityTheme" parent="Theme.AppCompat.NoActionBar">
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:textColorSecondary">@android:color/white</item>
<item name="android:windowActionBar">false</item>

public class MyGcmListenerService extends GcmListenerService {
@Override
public void onMessageReceived(String from, Bundle data) {
final String senderName = data.getString("sender");
final String message = data.getString("message");
if(senderName != null && senderName.equals("XXX")){
final AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.mainActivityTheme));
builder.setMessage(message)

})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
dialog.dismiss();
}
});
try {
new Thread() {
@Override
public void run() {
Looper.prepare();
final AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
alertDialog.show();
Looper.loop();
}
}.start();
} catch (Exception e) {
// TODO: handle exception

}
假的
真的
@android:彩色/白色
假的
我哪里做错了?我必须在活动中扩展AppCompatActivity
,因为我想使用setSupportActionBar()
方法将我的工具栏设置为操作栏
为了解决这个问题,我在类中做了一些更改,扩展了GcmListenerService
public class MyGcmListenerService extends GcmListenerService {
@Override
public void onMessageReceived(String from, Bundle data) {
final String senderName = data.getString("sender");
final String message = data.getString("message");
if(senderName != null && senderName.equals("XXX")){
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(message)
.setTitle("Alert!")
.setIcon(android.R.drawable.ic_dialog_alert)
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
dialog.dismiss();
}
});
try {
new Thread() {
@Override
public void run() {
Looper.prepare();
final AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
alertDialog.show();
Looper.loop();
}
}.start();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
我变了
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
到
这是我扩展gcmlistener服务的班级
<style name="mainActivityTheme" parent="Theme.AppCompat.NoActionBar">
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:textColorSecondary">@android:color/white</item>
<item name="android:windowActionBar">false</item>
</style>
public class MyGcmListenerService extends GcmListenerService {
@Override
public void onMessageReceived(String from, Bundle data) {
final String senderName = data.getString("sender");
final String message = data.getString("message");
if(senderName != null && senderName.equals("XXX")){
final AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.mainActivityTheme));
builder.setMessage(message)
.setTitle("Alert!")
.setIcon(android.R.drawable.ic_dialog_alert)
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog
dialog.dismiss();
}
});
try {
new Thread() {
@Override
public void run() {
Looper.prepare();
final AlertDialog alertDialog = builder.create();
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
alertDialog.show();
Looper.loop();
}
}.start();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
`
我的活动和AlertDialog.Builder使用的我的样式
<style name="mainActivityTheme" parent="Theme.AppCompat.NoActionBar">
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:textColorSecondary">@android:color/white</item>
<item name="android:windowActionBar">false</item>
</style>

为什么要尝试使用AppCompatActivity(用于带有操作栏的活动)当你有一个NoActionBar主题时?@TimCastelijns因为我需要设置支持ActionBar
,而我不能通过扩展Activity@TimCastelijns或者我有没有办法不扩展AppCompatActivity而setSupportActionBar
正常情况下,当您想使用操作栏时,您使用的主题不是NoActionBar,查看名称,原因应该是显而易见的获得以下错误:“无法添加窗口android.view.ViewRootImpl$W@2728b31--此窗口类型的权限被拒绝“有任何建议吗?啊,明白了:酷!为我工作。。。需要补充的是:正如这家伙所说:@moehward我当时离你很远,但是当我回来的时候,我发现你解决了这个问题。伟大的如果这个答案对你有帮助,别忘了投票:)
