android-activity - 在图像上创建按钮以打开新的 Activity onclick会崩溃

Question

我试图这样做:
当我单击imagebutton时，它打开了新的 Activity (名为:TakingPick.class)。
它崩溃了，我听不懂logcat。
我需要怎么做才能使其正常工作？

public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

}

@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;
}

public void sendMessage(View view) {
    Intent intent = new Intent(this, TakingPick.class);
    startActivity(intent);

}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    return false;

}

}

xml:activity_main

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


      android:background="@drawable/bridgebg"
          android:layout_height="match_parent"
          android:orientation="vertical" >

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="300dp"
    android:layout_height="300dp"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:src="@drawable/bridgenew" />

<ImageButton
    android:id="@+id/imageButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:onClick="sendMessage"
    android:layout_marginBottom="61dp"
    android:src="@drawable/loginfacebook" />

Answer 1

您遇到了内存不足的异常。您尝试加载的位图之一太大，导致内存泄漏。
如果您使用的是可绘制资源，请确保该资源位于正确的可绘制目录中。同时尝试减小图像尺寸和分辨率
