我搜索了所有互联网网站以修复此错误,但我不能。我只想用两个按钮Yes和No。

创建AlertDialog

这是我的代码:

import android.content.DialogInterface;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class DialogActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dialog);

    Button btnDialog= (Button) findViewById(R.id.btnDialog);
    btnDialog.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialogMessage();
        }
    });
}

private void showDialogMessage(){

    AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
    // Add the buttons
    builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            // User clicked OK button
        }
    });
    builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int id) {
            // User cancelled the dialog
        }
    });

    AlertDialog dialog = builder.create();
    dialog.show();
}
}

这是我的风格:

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="AppTheme.Base">
    <!-- Customize your theme here. -->
</style>

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

这是我的风格(第21节):

<resources>
<!-- extend one of the Theme.AppCompat themes -->
<style name="AppTheme" parent="AppTheme.Base">
    <!-- customize the color palette -->
    <item name="android:colorPrimary">@color/colorPrimary</item>
    <item name="android:colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="android:colorAccent">@color/colorAccent</item>
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:colorControlHighlight">@color/colorHighLight</item>
</style>
</resources>

这很明显:

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.saly.rastari" >   
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".DialogActivity"
            android:label="@string/title_activity_test"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>       
    </application>
</manifest>

当我点击对话框按钮时,我收到此错误:

我该如何解决这个问题?

如果您在另一个值文件夹中有另一个值文件夹,例如&#34; values-v11&#34;,&#34; values-v14&#34; ...也可以编辑主题在运行之前清理你的应用程序。

编辑: 从您的活动更改getApplicationContext()this

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());

AlertDialog.Builder builder = new AlertDialog.Builder(this);

因为对话框还应扩展Appcompat主题。

答案 1 :(得分:1)

如果有人遇到活动的这个问题,请尝试为您的活动明确配置主题。

<activity android:name=".activities.BLEControlActivity" android:theme="@style/Theme.AppCompat.DayNight"></activity>

答案 2 :(得分:1)

您遇到此错误是因为您的AlertDialog在活动时未使用AppCompat主题。要解决此问题,请使用您活动的this属性而不是getApplicationContext(),如下所示:

AlertDialog.Builder builder = new AlertDialog.Builder(DialogActivity.this);

应该始终使用活动名称,后跟.this,在这种情况下为DialogActivity.this,而不是仅使用this,因为如果对话框是在另一个类中创建的,则例如某种适配器,您将收到一个编译时错误,指出应使用Context而不是给定的适配器类。

在你的style.xml文件中添加以下代码 -

style.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AppTheme.Base" 
           parent="@style/Theme.AppCompat.Light">
    </style>
</resources>

还在您的活动中定义这样的主题

 <activity
            android:name=".DialogActivity"
            android:label="@string/title_activity_test"
            android:screenOrientation="portrait" 
            android:theme="@android:style/AppTheme.Dialog">

OR

<activity
            android:name=".DialogActivity"
            android:label="@string/title_activity_test"
            android:screenOrientation="portrait" 
            android:theme="@style/AppTheme">

清理项目并再次运行..

答案 4 :(得分:0)

我面对这样的案件,并设法解决了这个问题。在这里:

  • 在MainActivity类中定义警报对话框,例如:

public class MainActivity extends AppCompatActivity {

   AlertDialog.Builder alertDialog;

  • 然后在OnCreate()方法上对其进行初始化,如下所示:

alertDialog = new AlertDialog.Builder(this);

  • 然后,您可以在任意位置进行其余的警报对话框自定义,如图标,标题,消息。在我的情况下,我在倒数计时器的onFinish()中使用了它,如下所示:

public void onFinish() {

                alertDialog.setIcon(android.R.drawable.alert_light_frame);
                alertDialog.setTitle("You are done");
                alertDialog.setMessage("you got it");
                alertDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {

                        runTheCode();
                    }
                });
                alertDialog.show();

答案 5 :(得分:-1)

尝试在proguard规则中添加以下内容:

-keep public class com.google.android.gms.**
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

-dontwarn com.google.android.gms.**

如果您正在使用
