Question

我正在构建一个发送USSD命令以检查余额等的应用程序。当我尝试从项目点击启动活动时，应用程序很奇怪，这里是从图像按钮：我必须触摸两次才能启动活动。我不知道出了什么问题。

看看我的代码：

MainActivity.java：

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.RelativeLayout;


public class MainActivity extends AppCompatActivity {

    ImageView accountView;
    ImageView activationsView;
    ImageView servicesView;
    ImageView othersView;


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

    }

   public void openAccountView(View view){
        accountView = (ImageView) findViewById(R.id.accountView);
        accountView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(MainActivity.this, AccountActivity.class);
                startActivity(i);
            }
        });
    }

    public void openActivationsView(View view){
        activationsView = (ImageView) findViewById(R.id.activationsView);
        activationsView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(MainActivity.this, ActivationsActivity.class);
                startActivity(i);
            }
        });
    }

    public void openServicesView(View view){
        servicesView = (ImageView) findViewById(R.id.servicesView);
        servicesView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(MainActivity.this, ServicesActivity.class);
                startActivity(i);
            }
        });
    }

    public void openOthersView(View view){

    }


}

Answer 1

您通过onClick imageView调用openAccountView方法：

android:onClick="openAccountView"

因此，无需将onClicklistener添加到您的imageView。

删除onClicklistener中的openAccountView，使用以下代码：

public void openAccountView(View view){
          Intent i = new Intent(MainActivity.this, AccountActivity.class);
          startActivity(i);
    }

希望这有帮助。
