Question

我的主要活动中有两个图像，我想为每个图像点击显示新的活动。当我单击第一个Image时，它会启动第二个活动（Image2.class），而不是启动第一个活动（Image1.class）。为什么会这样？我想在单击image1时显示Image1.class Activity。同样，当我点击image2时，Image2.class活动。

public class MainActivity extends Activity   {

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

        ImageView image1 = (ImageView) findViewById(R.id.imageView1);

        ImageView image2 = (ImageView) findViewById(R.id.imageView2);

        image1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v1) {
                // TODO Auto-generated method stub

                Intent intent1 = new Intent(MainActivity.this,Image1.class);
                intent1.putExtra("image1Desc", "Text Description for IMAGE1!!!!!!!!!");
                startActivity(intent1);
                finish();
            }
        });

        image2.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v2) {
                // TODO Auto-generated method stub
                Intent intent2 = new Intent(MainActivity.this, Image2.class);
                intent2.putExtra("image2Desc", "Text Description for IMAGE2!!!!!!!");
                startActivity(intent2);
                finish();
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

Answer 1

我发现这个问题很简单。

MainActivity XML的imageView2在ImageView1之上重叠，这是不可见的。在我重新调整大小后，问题就解决了。

在主要活动XML

中

<ImageView
         android:id="@+id/imageView2"
         android:layout_width="200dp"
         android:layout_height="100dp"
         android:layout_alignLeft="@+id/imageView1"
         android:layout_below="@+id/imageView1"
         android:layout_marginTop="19dp"
         android:src="@drawable/b" />

onclickListeners不适用于两个不同的ImageView
