imageView.setOnClickListener(v -> {
// your code here
        });

你可以试试下面的代码:

Intent myIntent = new Intent();
FirstActivity.this.SecondActivity(myIntent);

    Intent in = new Intent(getApplicationContext(),SecondaryScreen.class);    
    startActivity(in);

    This is an explicit intent to start secondscreen activity.

实现视图。OnClickListener接口，并重写onClick方法。

ImageView btnSearch;

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search1);
        ImageView btnSearch = (ImageView) findViewById(R.id.btnSearch);
        btnSearch.setOnClickListener(this);
    }

@Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btnSearch: {
                Intent intent = new Intent(Search.this,SearchFeedActivity.class);
                startActivity(intent);
                break;
            }

点击按钮时:

loginBtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent= new Intent(getApplicationContext(), NextActivity.class);
        intent.putExtra("data", value); //pass data
        startActivity(intent);
    }
});

从nex战术vity.class接收额外的数据:

Bundle extra = getIntent().getExtras();
if (extra != null){
    String str = (String) extra.get("data"); // get a object
}

点击按钮打开活动的最简单的方法是:

在res文件夹下创建两个活动，在第一个活动中添加一个按钮，并为onclick函数命名。 每个活动应该有两个java文件。 下面是代码:

MainActivity.java

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.content.Intent;
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void goToAnotherActivity(View view) {
        Intent intent = new Intent(this, SecondActivity.class);
        startActivity(intent);
    }
}

SecondActivity.java

package com.example.myapplication;
import android.app.Activity;
import android.os.Bundle;
public class SecondActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity1);
    }
}

AndroidManifest.xml(只需将此代码块添加到现有代码中)

 </activity>
        <activity android:name=".SecondActivity">
  </activity>
