Android 其他类单击ImageView

我有个问题。所以我有几个活动，在其中一个活动中，我有6个ImageView，我为每个人设置了一个来自xml的“onClick”。我想知道如何检查图像是否被点击，然后显示在另一个活动中。这是我写的，它还没有完成，我做得好吗？如果是，您能帮助我将这些图像“导入”到最终活动中吗

public ImageView imageSelected;
private Intent i = new Intent(this, MemeSecondStep.class);

public void onFirstPicClick(View view) {
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPunu);
    }

    public void onSecondPicClick(View view) {
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPdoi);
    }

    public void onThirdPicClick(View view) {
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPtrei);
    }

    public void onFourthPicClick(View view) {
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPpatru);
    }

    public void onFifthPicClick(View view) {
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPcinci);
    }

    public void onSixthPicClick(View view) {
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPsase);
    }

您可以将单击的图像放入意图中，并将其发送到其他类似的活动中

public ImageView imageSelected;
private Intent i = new Intent(this, MemeSecondStep.class);

public void onFirstPicClick(View view) {
        i.putExtra("firstImageKey","firstImage");
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPunu);
    }

在您的第二个活动中，必须有一个ImageView，当您从intent中获取哪个图像时，单击“设置图像源”以获得所需的图像

有了这句话，你可以从意图中获得额外的信息，并设置渴望的形象

 Intent intent = getIntent();
 String clickedImageName = intent.getStringExtra("firstImageKey");
 if(clickedImageName.equals("firstImage"){
  //set desire image
 }

你的案子有很多解决办法，但这是我想到的第一个

更新

下面是可以解决您问题的第二个解决方案：

首先，在包含六个ImageView的xml中，必须像这样为每个ImageView设置标记

public ImageView imageSelected;
private Intent i = new Intent(this, MemeSecondStep.class);

public void onFirstPicClick(View view) {
        i.putExtra("firstImageKey","firstImage");
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPunu);
    }

first_activity.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

        android:src="@drawable/ic_launcher"
        android:tag="image2"/>

    <ImageView
        android:id="@+id/imageView3"
        android:layout_width="wrap_content"

然后，当您成功创建意图时，请在SecondActivity中从中获取额外信息，并根据您从第一个活动中单击的图像将desire image source设置为SecondActivity中的imageView，如下所示

public ImageView imageSelected;
private Intent i = new Intent(this, MemeSecondStep.class);

public void onFirstPicClick(View view) {
        i.putExtra("firstImageKey","firstImage");
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPunu);
    }

SecondActivity.java

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private ImageView image1;
    private ImageView image2;
    private ImageView image3;
    private ImageView image4;
    private ImageView image5;
    private ImageView image6;
    private String yourImageTag="";

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

        initializeLayoutElements();

        image1.setOnClickListener(this);
        image2.setOnClickListener(this);
        image3.setOnClickListener(this);
        image4.setOnClickListener(this);
        image5.setOnClickListener(this);
        image6.setOnClickListener(this);
    }

    private void initializeLayoutElements(){
        image1= (ImageView)findViewById(R.id.imageView1);
        image2= (ImageView)findViewById(R.id.imageView2);
        image3= (ImageView)findViewById(R.id.imageView3);
        image4= (ImageView)findViewById(R.id.imageView4);
        image5= (ImageView)findViewById(R.id.imageView5);
        image6= (ImageView)findViewById(R.id.imageView6);
    }


    @Override
    public void onClick(View v) {
        Intent intent = new Intent(MainActivity.this, SecondActivity.class);
        yourImageTag = v.getTag().toString();
        intent.putExtra("imageTag",yourImageTag);
        startActivity(intent);
    }
}

public class SecondActivity extends AppCompatActivity  {

    private ImageView yourNewImage;

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

    }

    private void initializeLayoutElements(){
        yourNewImage= (ImageView)findViewById(R.id.imageView1);
    }

    private void getDataFromIntent(){
        Intent intent = getIntent();
        String yourImageTag = intent.getStringExtra("imageTag");
        switch (yourImageTag){
            case "image1":
                Toast.makeText(SecondActivity.this, "image1", Toast.LENGTH_SHORT).show();
                //Here you can set your desire recourse for yourNewImage
                break;
            case "image2":
                Toast.makeText(SecondActivity.this, "image2", Toast.LENGTH_SHORT).show();
                //Here you can set your desire recourse for yourNewImage

                //Here you can set your desire recourse for yourNewImage
                break;
            case "image4":
                Toast.makeText(SecondActivity.this, "image4", Toast.LENGTH_SHORT).show();
                //Here you can set your desire recourse for yourNewImage
                break;
            case "image5":
                Toast.makeText(SecondActivity.this, "image5", Toast.LENGTH_SHORT).show();
                //Here you can set your desire recourse for yourNewImage
                break;
            case "image6":
                Toast.makeText(SecondActivity.this, "image6", Toast.LENGTH_SHORT).show();

                break;
        }
    }
}

第二个活动的xml如下所示

public void onFirstPicClick(View view) {

但这只是针对您的测试用例，您必须更改它。希望此更新对您有所帮助

您可以将单击的图像放入intent中，并将其发送到其他类似的活动中

public ImageView imageSelected;
private Intent i = new Intent(this, MemeSecondStep.class);

public void onFirstPicClick(View view) {
        i.putExtra("firstImageKey","firstImage");
        startActivity(i);
        imageSelected = (ImageView) findViewById(R.id.goitiPunu);
    }
