Question

我如何在cardview上的这个标题中做这个蓝色背景？

我尝试使用蓝色背景进行线性布局，但这会使得安卓程序设置为SO 19或更糟糕的崩溃应用程序

此cardview是listview项目的模板

Cardview：

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="100dp">

    <ImageView
        android:id="@+id/imagem"
        android:layout_width="100dp"
        android:layout_height="match_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_marginBottom="5dp"
        android:layout_marginLeft="5dp"
        android:layout_marginRight="5dp"
        app:srcCompat="@drawable/a_receber" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="16dp"
        android:layout_marginLeft="-8dp"
        android:layout_toRightOf="@+id/imagem"
        android:background="@drawable/bordas_cardview_azul"/>

    <TextView
        android:id="@+id/lista_personalizada_vencimento"
        android:layout_width="300dp"
        android:textColor="#fff"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_toEndOf="@+id/imagem"
        android:layout_toRightOf="@+id/imagem"
        android:text="Titulo"
        android:textSize="11sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/lista_personalizada_emissao"
        android:layout_width="300dp"
        android:layout_height="wrap_content"
        android:layout_below="@+id/lista_personalizada_vencimento"
        android:layout_toEndOf="@+id/imagem"
        android:layout_toRightOf="@+id/imagem"
        android:text="telefone1"
        android:textSize="12sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/lista_personalizada_nome"
        android:layout_width="300dp"
        android:layout_height="wrap_content"
        android:layout_below="@+id/lista_personalizada_emissao"
        android:layout_toEndOf="@+id/imagem"
        android:layout_toRightOf="@+id/imagem"
        android:text="celular"
        android:textSize="12sp" />

    <TextView
        android:id="@+id/lista_personalizada_deve"
        android:layout_width="300dp"
        android:layout_height="wrap_content"
        android:layout_below="@+id/lista_personalizada_nome"
        android:layout_toEndOf="@+id/imagem"
        android:layout_toRightOf="@+id/imagem"
        android:text="renda"
        android:textSize="12sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/lista_personalizada_valorini"
        android:layout_width="300dp"
        android:layout_height="wrap_content"
        android:layout_below="@+id/lista_personalizada_deve"
        android:layout_toEndOf="@+id/imagem"
        android:layout_toRightOf="@+id/imagem"
        android:text="limite"
        android:textSize="12sp" />

    <TextView
        android:id="@+id/lista_personalizada_status"
        android:layout_width="300dp"
        android:layout_height="wrap_content"
        android:layout_below="@+id/lista_personalizada_valorini"
        android:layout_toEndOf="@+id/imagem"
        android:layout_toRightOf="@+id/imagem"
        android:text="bandeira"
        android:textSize="12sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/lista_personalizada_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/lista_personalizada_status"
        android:layout_toEndOf="@+id/imagem"
        android:layout_toRightOf="@+id/imagem"
        android:text="id"
        android:visibility="gone" />

</RelativeLayout>

线性布局的drawable / bordas_cardview_azul

 <shape
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:shape="rectangle" >

 <solid
    android:color="#1874CD"/>

<corners
    android:topRightRadius="4dp"/>

</shape>

当我尝试使用SO 20或更好的Android启动时，它开始正常，没有问题，但以前的停止工作

适配器列表视图

  public class AdapterContasPersonalizado extends BaseAdapter {

private final List<Curso2> cursos;
private final contas act;

public AdapterContasPersonalizado(List<Curso2> cursos, contas act) {
    this.cursos = cursos;
    this.act = act;
}

@Override
public int getCount() {
    return cursos.size();
}

@Override
public Object getItem(int position) {
    return cursos.get(position);
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
 //line 40 below
    View view = act.getLayoutInflater().inflate(R.layout.lista_contas_personalizada, parent, false);

    Curso2 curso = cursos.get(position);

    ImageView imagem = (ImageView)
            view.findViewById(R.id.imagem);
    TextView vencimento = (TextView)
            view.findViewById(R.id.lista_personalizada_vencimento);
    TextView emissao = (TextView)
            view.findViewById(R.id.lista_personalizada_emissao);
    TextView nome = (TextView)
            view.findViewById(R.id.lista_personalizada_nome);
    TextView devendo = (TextView)
            view.findViewById(R.id.lista_personalizada_deve);
    TextView valorini = (TextView)
            view.findViewById(R.id.lista_personalizada_valorini);
    TextView status = (TextView)
            view.findViewById(R.id.lista_personalizada_status);
    TextView id = (TextView)
            view.findViewById(R.id.lista_personalizada_id);

    vencimento.setText(curso.getVencimento());
    emissao.setText(curso.getEmissao());
    nome.setText(curso.getNome2());
    devendo.setText(curso.getDevendo());
    valorini.setText(curso.getValorini());
    status.setText(curso.getStatus2());
    id.setText(curso.getId2());

    return view;
}
}

错误仅发生在列表视图中的插入中，因为正常使用cardview时，它不会显示错误

Answer 1

这种膨胀异常是由于您的可绘制资产规模较大造成的。删除背景drawable到适当的文件夹，如drawable-hdpi或使用颜色代码来获得正确的颜色。
