我正在尝试使用URLwith Universal Image Loader和zoomwith 来实现加载图像TouchImageView Mike Ortiz.但是在尝试查看图像时,会显示黑屏.我已检查过网址是否正确.我是否在那里看到TextView ...

我究竟做错了什么？

ImagePagerActivity.java

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.activity_fullscreen_view);

    Bundle bundle = getIntent().getExtras();
    assert bundle != null;

    String[] imageUrls = bundle.getStringArray("urls");
    int pagerPosition = bundle.getInt("pos", 0);
    tipo = bundle.getString("tipo");
    monumento = bundle.getString("monumento");
    num = bundle.getInt("num");

    for(int i = 0; i < imageUrls.length; i++) {
        // URLS with data
        Toast.makeText(this, "URL = " + imageUrls[i], 0).show();
    }

    if (savedInstanceState != null) {
        pagerPosition …

我用Navigation Drawerin 创建了一个应用程序BaseActivity.一切正常,除了改变标题Action Bar.标题会更改一秒钟,但在打开新活动时会显示原始标题.

可能是什么错误？谢谢

BaseActivity

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    PerfilAdapter.iniciarBaseDatos(this);
    perfilObj = PerfilAdapter.selectPerfil(1);

    requestWindowFeature(Window.FEATURE_ACTION_BAR);

    cargarActionBar();
    cargarDrawerLayout(savedInstanceState);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu, menu);

    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    if (mDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    }

    switch (item.getItemId()) {

    case R.id.menuOpcSonidos:

                   ...
                   return true;

    case R.id.menuOpcCambiarColor:
        ...
        return true;

    default:
        return super.onOptionsItemSelected(item);
    }
}

@Override
public boolean onPrepareOptionsMenu(Menu menu) {

    menu.findItem(R.id.menuOpcSonidos)
        .setTitle(getResources().getString(R.string.sonidoOnOff) + " " + perfilObj.getSonidos()); …

我在我的应用程序中有一个自定义可扩展,我希望标题(5dp)和子(1dp)的分隔符高度不同.我怎么办？这是我的代码:

bus_info.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<ExpandableListView
    android:id="@+id/expandableBus"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="3dp"
    android:divider="@drawable/expandable_borde_padre"
    android:childDivider="@drawable/expandable_borde_hijo"
    android:groupIndicator="@drawable/expandable"
    android:scrollbars="none"/>

</LinearLayout>

expandable.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
      <item android:drawable="@drawable/expandable_abajo" android:state_empty="true"/>
      <item android:drawable="@drawable/expandable_arriba" android:state_expanded="true"/>
      <item android:drawable="@drawable/expandable_abajo" />
</selector>

expandable_borde_padre.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" 
      android:shape="rectangle">
     <solid android:color="@color/negro"/>
     <size android:height="1dp"/>
</shape>

expandable_borde_hijo.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">
    <solid android:color="@color/blanco"/>
    <size android:height="1dp"/>
</shape>

如果我在expandable_borde_padre中更改为5dp也会更改子项

expandable_hijo.java

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="55dip"
android:orientation="vertical" 
android:background="#000000">

<TextView
    android:id="@+id/lblListItem"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textSize="14sp"
    android:paddingTop="5dp"
    android:paddingBottom="5dp"
    android:textColor="#FFFFFF"/>

</LinearLayout>

expandable_padre.java

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fondoExpandablePadre"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="8dp" 
android:background="#000000">


<TextView
    android:id="@+id/lblListHeader"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:paddingLeft="1dp" …
