Question

我还是初学者在android中。如何让android onclicklistener进行下一个活动，我的意思是，我创建了RegisterActivity，当用户注册时，程序应该是MainActivity但它转到SingleMenuItemActivity。谁能告诉我我想做什么？非常感谢你。抱歉我的英语不好。

package unai.skripsi.bandungtourgiude;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

import android.widget.TextView;

public class SingleMenuItemActivity  extends Activity {

// JSON node keys
private static final String in_nama_tempat = "nama_tempat";
private static final String in_alamat_tempat = "alamat_tempat";
private static final String in_no_tempat = "no_tempat";
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.single_list_item);

    // getting intent data
    Intent in = getIntent();

    // Get JSON values from previous intent
    String nama = in.getStringExtra(in_nama_tempat);
    String alamat = in.getStringExtra(in_alamat_tempat);
    String nomor = in.getStringExtra(in_no_tempat);

    // Displaying all values on the screen
    TextView lblName = (TextView) findViewById(R.id.nama_tempat);
    TextView lblCost = (TextView) findViewById(R.id.alamat_tempat);
    TextView lblDesc = (TextView) findViewById(R.id.no_tempat);

    lblName.setText(nama);
    lblCost.setText(alamat);
    lblDesc.setText(nomor);

    Button map = (Button) findViewById(R.id.button1);
       map.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            startActivity(new Intent(SingleMenuItemActivity.this, Pariwisata.class));
        }
    });

Answer 1

Intent过滤器确定要启动的内容。

按以下方式更改您的清单

<activity
    android:name=".MainActivity"
    android:configChanges="orientation|keyboardHidden"
    android:label="@string/app_name" >

<intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

并删除

<intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Answer 2

在btnRegister onClick侦听器中，删除 startActivity 和完成。

Intent i = new Intent(getApplicationContext(), MainActivity.class);
// Registering user on our server                   
// Sending registraiton details to MainActivity
i.putExtra("name", name);
i.putExtra("email", email);
RegisterActivity.this.startActivity(i);

如果您不想在历史堆栈中使用RegisterActivity，请在清单文件中为活动标记设置属性android:noHistory=true，而不是finish（）方法。
