Java 更改布局的组件

我是android初学者，我有一个

gridview

图像，当你点击图像时，它会将你移动到

SecondActivity

。在

SecondActivity

中，我有一些与每个图像相关的信息。

SecondActivity

的布局对于所有图像都是相同的，我想更改同一布局中每个图像的标题、文本和图像。 我使用了

setTitle

、

setxt

和

setImageDrawable（）

，但它没有改变。我会的，但我的一些代码行，也许它将是完全错误的，所以如果它是，请引导我到一个简单的源代码

在产品类别中

public int getImageId() {
        return imageId;
    }

    public void setImageId(int imageId) {
        this.imageId = imageId;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

在主活动中

public List<Product> getProductList() {
        //pseudo code to get product, replace your code to get real product here
        productList = new ArrayList<>();
        productList.add(new Product(R.drawable.ii1, " Story Name", "This is description 1"));
        productList.add(new Product(R.drawable.i2, "Story Name", "This is description 2"));
        productList.add(new Product(R.drawable.i3, "Story Name", "This is description 3"));
        productList.add(new Product(R.drawable.i4, "Story Name", "This is description 4"));
        productList.add(new Product(R.drawable.i5, "Story Name", "This is description 5"));
        productList.add(new Product(R.drawable.i6, "Story Name", "This is description 6"));
        productList.add(new Product(R.drawable.i8, "Story Name", "This is description 8"));
        productList.add(new Product(R.drawable.i9, "Story Name", "This is description 9"));
        productList.add(new Product(R.drawable.i10, "Story Name", "This is description 10"));

        return productList;
    }

 mToolbar = findViewById(R.id.toolbar);
        img  = findViewById(R.id.imageView6);
         t=findViewById(R.id.textView4);
        Bundle bundle = getIntent().getExtras();

        if (bundle != null) {
            mToolbar.setTitle(bundle.getString("title"));

            if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")) {
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.ii1));
                t.setText(bundle.getString("title"));
            }

            else if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")){
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.i2));

            }

            else if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")) {
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.i3));

            }

            else if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")) {
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.i4));

            }

            else if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")) {
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.i5));

            }

            else if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")) {
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.i6));

            }

            else if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")) {
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.i8));

            }

            else if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")) {
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.i9));

            }

            else if (mToolbar.getTitle().toString().equalsIgnoreCase("Story Name")) {
                img .setImageDrawable(ContextCompat.getDrawable(SecondActivity.this, R.drawable.i10));

            }


        }
    }

}

Intent i= new Intent(MainActivity.this,SecondActivity.class);
                    Bundle b= new Bundle();
                    b.putString("Story Name", productList.get(position).getTitle().toString());
                    i.putExtras(b);
                    startActivity(i);

TextView t =findViewById(R.id.textView4);
Bundle b=getIntent().getExtras();
String story=b.getString("Story Name");
t.setText(story);

第二个活动XML

<ImageView
        android:id="@+id/imageView6"
        android:layout_width="160dp"
        android:layout_height="180dp"
        android:layout_marginLeft="13dp"
        android:layout_marginStart="13dp"
        android:layout_marginTop="60dp"
        app:srcCompat="@drawable/ii1"
        tools:ignore="ContentDescription"
        android:layout_below="@+id/appBarLayout"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />

    <TextView
        android:id="@+id/textView4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageView6"
        android:layout_marginLeft="15dp"
        android:layout_marginStart="15dp"
        android:layout_marginTop="22dp"
        android:layout_toRightOf="@+id/imageView6"
        android:textSize="14sp"
        tools:ignore="HardcodedText,RtlHardcoded" />

单击一个图像时，转到单击事件并保持图像的位置。然后将列表中的信息发送到第二个活动。

这正在与我一起工作 我将文本发送到第二个活动，如下所示

main活动

我也在图片和标题上使用它，当我发送它时，它没有完成。对不起，我的错误您的意思是我将使用intent传递信息，然后putExtra并启动活动Yes。这就是我要说的
