而不是在清单错误中声明活动被抛出

debugcn 发表于 Dev

如图

我有两个活动显示和查看。我已经在manifest.xml中声明了视图活动，但是随后还引发了抛出错误并意外关闭

manifest.xml

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">
    <activity
        android:name="com.abhishekp.passmanage.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="com.abhishekp.passmanage.Create" > </activity>
    <activity android:name="com.abhishekp.passmanage.Details" > </activity>
    <activity android:name="com.abhishekp.passmanage.Setting" > </activity>
    <activity android:name="com.abhishekp.passmanage.Show" > </activity>
    <activity android:name="com.abhishekp.passmanage.View"> </activity>


   </application>

</manifest>

show.xml

在单击任何按钮时，我将配置文件名称传递为

    public class Show extends Activity {

Button showhome,atm,bank,mail,mobile,other,personal,social;
String profile;



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

//buttons id declarations

    showhome.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            Intent main = new Intent(getApplicationContext(), MainActivity.class);
            profile = "SHOW";
            main.putExtra("key", profile);
            startActivityForResult(main, 0);
        }

    });

    atm.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {

            Intent d1 = new Intent(getApplicationContext(), View.class);
            profile = "ATM";
            d1.putExtra("key", profile);
            startActivityForResult(d1, 0);
        }
    });

    bank.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            profile="BANK";
            Intent d2 = new Intent(getApplicationContext(), View.class);
            d2.putExtra("key", profile);
            startActivityForResult(d2, 0);
        }
    });

    mail.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            profile="MAIL";
            Intent d3 = new Intent(getApplicationContext(), View.class);
            d3.putExtra("key", profile);
            startActivityForResult(d3, 0);
        }
    });

在视图活动中，我只有1个textview，在视图活动中，我试图获取该值

package com.abhishekp.passmanage;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class View extends Activity {

TextView profilename;
String profile;

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


    profilename = (TextView)findViewById(R.id.profilename);


    Bundle extras = getIntent().getExtras();
    if (extras != null) 
    {
        profile = extras.getString("key");
        profilename.setText("Profile : " +profile);
    }

}

}

但它在日志猫中抛出错误为

因为View类已经在android中可用，所以更改类名称或使用setClass并setComponent以以下方式启动Activity：

Intent intent = new Intent();
intent.setClassName("com.abhishekp.passmanage", 
                                          "com.abhishekp.passmanage.View");
intent.setComponent(new ComponentName("com.abhishekp.passmanage",
                                          "com.abhishekp.passmanage.View"));
startActivity(intent);
