目前我有:

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="15:22:33 \nApr 13 1999"
                        android:textColor="#FFFFFFFF" 

        android:textAppearance="?android:attr/textAppearanceSmall" />

    <TextView
        android:id="@+id/comment"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="5dip"
        android:background="@drawable/incoming_message_buble"
        android:paddingLeft="10dip"
        android:text="Hello bubbles!"
        android:textColor="@android:color/primary_text_light" />

它工作正常。

这是适配器代码:

public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    if (row == null) {
        LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.activity_sms_row_layout, parent, false);
    }

    wrapper = (LinearLayout) row.findViewById(R.id.wrapper);

    OneComment coment = getItem(position);

    countryName = (TextView) row.findViewById(R.id.comment);

    countryName.setText(coment.comment);


    countryName.setBackgroundResource(coment.left ? R.drawable.incoming_message_buble : R.drawable.outgoing_message_buble);
    wrapper.setGravity(coment.left ? Gravity.LEFT : Gravity.RIGHT);

    return row;
}

我必须更改顺序,对于左重力,我需要首先显示 textview 注释,然后为重力右显示 textView1,保持 xml 设置。

请指教。

我建议使用多个布局,而不是不断地重新组织每一行的布局。覆盖这两个方法:

@Override
public int getItemViewType(int position) {
    return getItem(position).left ? 0 : 1;
}

@Override
public int getViewTypeCount() {
    return 2;
}

并修改您的getView()

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if(getItemViewType == 0) {
        // Use the left layout
    } else {
        // Use the right layout
    }
}
