我想构建一个可以生成多个textview的应用程序,它们都适合指定的布局。 但是一旦该行已满而不是在新行继续,它就不会显示其余的文本视图
我的MainActivity.java:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList<String> urls=new ArrayList<String>(); //to read each line
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.sell);
// Add textview 1
for (int i=0;i<10;i++){
LinearLayout.LayoutParams layoutParams1 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
layoutParams1.setMargins(10, 10, 10, 10);
TextView textView1 = new TextView(this);
textView1.setLayoutParams(layoutParams1);
textView1.setText("TextView1\n2");
textView1.setBackgroundColor(0xFF3EB427); // hex color 0xAARRGGBB
textView1.setPadding(10, 10, 10, 10);// in pixels (left, top, right, bottom)
linearLayout.addView(textView1);
}
LinearLayout linearLayout2 = (LinearLayout) findViewById(R.id.buy);
LinearLayout.LayoutParams layoutParams2 = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
for (int i=0;i<2;i++){
layoutParams2.setMargins(10, 10, 10, 10);
TextView textView1 = new TextView(this);
textView1.setLayoutParams(layoutParams2);
textView1.setText("TextView2");
textView1.setBackgroundColor(0xFFB60612); // hex color 0xAARRGGBB
textView1.setPadding(20, 20, 20, 20);// in pixels (left, top, right, bottom)
linearLayout2.addView(textView1);
}
}
}
我的xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:background="#ffffff"
android:layout_height="match_parent"
android:id="@+id/mymain"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.ohad.tradertracker.MainActivity"
android:weightSum="1">
<LinearLayout
android:id="@+id/stats"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="101dp">
</LinearLayout>
<LinearLayout
android:id="@+id/sell"
android:layout_weight=".5"
android:fillViewport="true"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
如何生成未知数量的textview并使用所有布局大小???
答案 0 :(得分:0)
我认为你的xml布局存在问题。这样做,告诉我它是否有效。 你可以做两件事:
或者你可以提及 weightSum 为2。并且在布局中确保您已将 layout_weight提及为。
