我正在进行布局,我必须在垂直线性布局中填充textView programmaticaly。但是我的一些textView内容对于我的屏幕尺寸而言太宽而且它们不可见。这是我的布局
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior">
<HorizontalScrollView
android:layout_width="320px"
android:layout_height="match_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/diff_layout"
android:layout_width="320px"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
</HorizontalScrollView>
</ScrollView>
这是代码,我以编程方式填充线性布局: -
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.diff_layout);
String[] splitLines = content.split("\n");
for(int i=0;i<splitLines.length;i++){
TextView textView = new TextView(this);
textView.setSingleLine(true);
textView.setLines(1);
//textView.setHorizontallyScrolling(true);
textView.setText(splitLines[i]);
//textView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT ));
textView.setWidth(LinearLayout.LayoutParams.WRAP_CONTENT);
/*textView.setMovementMethod(new ScrollingMovementMethod());
textView.setHorizontallyScrolling(true);*/
linearLayout.addView(textView);
}
请告诉我我在哪里做错了
答案 0 :(得分:1)
经过多次打击和试验后,我想出了正确的解决方案: -
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<HorizontalScrollView android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/diff_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
</HorizontalScrollView>
</android.support.v4.widget.NestedScrollView>
和我的java片段: -
LinearLayout linearLayout =(LinearLayout) findViewById(R.id.diff_layout);
String[] splitLines = content.split("\n"); for(int i=0;i<splitLines.length;i++){ TextView textView = new TextView(this); textView.setText(splitLines[i]); textView.setMaxLines(1); textView.setMovementMethod(new ScrollingMovementMethod()); linearLayout.addView(textView); }
