Question

希望通过 LOOP 或动态TextView Genrate在此子LinearLayout中实现此布局 android：layout_weight =＆＃34; 0.5＆＃34;

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/child_layout"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/text_range_min"
        style="@android:style/TextAppearance.Small"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginLeft="100px"
        android:layout_weight="0.5"
        android:gravity="left"
        android:text="1" />

    <TextView
        android:id="@+id/text_range_min2"
        style="@android:style/TextAppearance.Small"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:gravity="left"
        android:text="2" />

    <TextView
        android:id="@+id/text_range_min3"
        style="@android:style/TextAppearance.Small"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:gravity="left"
        android:text="" />

    <TextView
        android:id="@+id/text_range_min4"
        style="@android:style/TextAppearance.Small"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:gravity="left"
        android:text="3" />

    <TextView
        android:id="@+id/text_range_max"
        style="@android:style/TextAppearance.Small"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="0.5"
        android:gravity="right"
        android:text="4" />

</LinearLayout>

它可能有更多或更少的文本视图所以我想通过循环动态添加，并为所有文本视图分配权重

我正在使用它但不会设置重量

 LinearLayout MainLL= (LinearLayout) findViewById(R.id.child_layout);
    for(int i=0; i<5; i++){
        TextView text = new TextView(this);
        text.setText(""+i); // <-- does it really compile without the + sign?
        text.setGravity(Gravity.LEFT);
        text.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT,0.5f));
        MainLL.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));



        MainLL.addView(text);
    }

更改为代码中的text.setLayoutParams(new LinearLayout.LayoutParams(0, LinearLayout.LayoutParams.WRAP_CONTENT, 0.5f));。

设置TextView 0
设置TextView 0.5f

试试这个。

LinearLayout MainLL = (LinearLayout) findViewById(R.id.child_layout);
for (int i = 0; i < 5; i++) {
        TextView text = new TextView(this);
        text.setText("" + i);
        text.setGravity(Gravity.LEFT);
        LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(0, LinearLayout.LayoutParams.WRAP_CONTENT, 0.5f);
        // add margin
        layoutParams.setMargins(10,10,10,10);
        text.setLayoutParams(layoutParams);
        MainLL.addView(text);
}

在JAVA中实现布局
