[英]Android - Activity persist as destroyed after call startActivity
This is the problem´s cenary: 这是问题的场景:
The Activity "A" have a button than call startActivity B. 活动“ A”具有一个按钮,而不是调用startActivityB。
The Activity "B" have a button then call finish(). 活动“ B”有一个按钮,然后调用finish()。 So the app show Activity "A" again. 因此,应用再次显示活动“ A”。
Now, If i call activity "B" the property mDestroyed = true 现在,如果我将活动称为“ B”,则属性mDestroyed = true
The problem: When i access B a second time B is destroyed 问题: 当我第二次访问B时,B被破坏了
Why B continue destroyed after i call startActivity? 为什么在我调用startActivity之后B继续被破坏?
Someone can help me? 有人可以帮我吗?
ManifestFile: 清单文件:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="br.com.xxxxxx">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="xxx"
android:supportsRtl="false"
android:theme="@style/MyMaterialTheme">
<activity
android:name=".BaseActivity"
android:screenOrientation="portrait" />
<activity
android:name=".A"
android:screenOrientation="portrait" />
<activity
android:name=".B"
android:screenOrientation="portrait" />
</application>
</manifest>
Activity B method: 活动B的方法:
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
Activity A method: 活动A方法:
@Override
public void onClick(View view) {
startActivity(new Intent(MainActivity.this, B.class));
}
finish()
method calls onDestroy()
of activity . finish()
方法调用activity的onDestroy()
。 Replace finish()
with 将finish()
替换为
startActivity(new Intenet(CurrentActivity.this, NewActivity.class));
Your current activity will be in background. 您当前的活动将在后台进行。
