我需要創建一個必須在下周通過的活動?；顒邮怯?2 個按鈕（相機和地圖）制作一個主頁，這意味著我必須使用意圖功能來工作這個應用程序。但是我有一個問題，相機按鈕可以正常工作，但我的地圖無法正常工作，這就是我在這里尋求幫助的原因。我試過地圖=(Button) findViewById(R.id.map); map.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { openMapsActivity(); } });然后public void openMapsActivity() { Intent intent = new Intent(this, MapsActivity.class); startActivity(intent); }

像這樣更新您的清單應用程序：
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">

The API key for Google Maps-based APIs is defined as a string resource.
(See the file "res/values/google_maps_api.xml").
Note that the API key is linked to the encryption key used to sign the APK.
You need a different API key for each encryption key, including the release key that is used to
sign the APK for publishing.
You can define the keys for the debug and release targets in src/debug/ and src/release/.

<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/google_maps_key" />
<activity
android:name=".MainActivity"
android:label="@string/title_activity_maps">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity

android:screenOrientation="portrait" />
</application>
