Question

我的xml如下所示我想以编程方式将图像视图和文本视图添加到给定的xml。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:padding="25dip" >

 <TextView
       android:id="@+text1"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_marginBottom="12dip"
       android:text="@string/app_name"
       android:textSize="24.5sp" />

</LinearLayout>

但我希望以编程方式输出如下：即线性布局包含图像视图和旧文本视图，并将下面的linearlayout添加到新的textview。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:padding="25dip" >

 <TextView
       android:id="@+name"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_marginBottom="12dip"
       android:text="@string/app_name"
       android:textSize="24.5sp" />

   <LinearLayout 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="25dip" >

    <ImageView
           android:layout_width="wrap_content"
           android:layout_height="60dp"
           android:layout_marginBottom="12dip"

           android:src="@drawable/app_icon_big" />
    <TextView
       android:id="@+text1"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_marginBottom="12dip"
       android:text="@string/app_name"
       android:textSize="24.5sp" />

   </LinearLayout>

</LinearLayout>

Answer 1

请尝试这种方式，希望这有助于您解决问题。

<强> main.xml中

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/outerLinearLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="25dp" >

    <TextView
        android:id="@+id/text1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="12dp"
        android:text="@string/app_name"
        android:textSize="24.5sp" />

</LinearLayout>

<强> MainActivity.java

public class MyActivity extends Activity {

    private LinearLayout outerLinearLayout;
    private TextView text1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        outerLinearLayout = (LinearLayout) findViewById(R.id.outerLinearLayout);
        text1 = (TextView) findViewById(R.id.text1);

        LinearLayout innerLinearLayout = new LinearLayout(this);

        ImageView imageView = new ImageView(this);
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        params.bottomMargin=12;
        imageView.setLayoutParams(params);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        imageView.setImageResource(R.drawable.ic_launcher);
        innerLinearLayout.addView(imageView);
        TextView textView = new TextView(this);
        textView.setTextSize((float) 24.5);
        textView.setText("New Text View");
        textView.setLayoutParams(params);
        outerLinearLayout.removeAllViews();
        innerLinearLayout.addView(text1);
        outerLinearLayout.addView(textView);
        outerLinearLayout.addView(innerLinearLayout);
    }
}

更改内部布局

<LinearLayout 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="25dip" >

通过

<LinearLayout 
    android:id="@+id/internal_image_textView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="25dip"
    android:visibility="gone" >

然后当你想要展示

时

findViewById(R.id.internal_image_textView).setVisibility(View.VISIBLE)
