MainActivity类

主要活动工作正常但是当我点击登录时它停止了行动

package com.example.dinidev.ecom;
import android.content.Context;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
Button signin;
final Context context = this;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    addListenerOnButton();
}

private void addListenerOnButton() {
    /** Login Button Click */
    signin = (Button) findViewById(R.id.signin);
    signin.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(context, Signin.class);
            startActivity(intent);
        }
    });
 }

登录类

当我调试该行时，它显示了save instance：null message

package com.example.dinidev.ecom;
import android.app.Activity;
import android.os.Bundle;
public class Signin extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.login_page);
}
}

Answer 1

您必须在应用程序中包含multiDex。在您的清单中，您尚未包含 MulitiDexApplication 。

在您的错误代码中。看到这一行。

Didn't find class "android.support.v4.view.animation.FastOutSlowInInterpolator" on path: DexPathList[

将此添加到您的依赖项。

compile 'com.android.support:multidex:1.0.1'

在Gradle中添加multiDexEnabled true。

android {
    defaultConfig {
        ...
        minSdkVersion 21 
        targetSdkVersion 26
        multiDexEnabled true    // add this line
    }
    ...
}

在manifest添加multiDex应用程序类中。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp">
    <application
            android:name="android.support.multidex.MultiDexApplication" >
        ...
    </application>
</manifest>

最后清理并重建您的项目。
