Question

android似乎无缘无故地切断了我的文本视图。

围绕该区域的XML是：

<HorizontalScrollView
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:background="@android:color/background_dark"
    android:layout_width="fill_parent">
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:id="@+id/suggestions">
        </LinearLayout>
</HorizontalScrollView>

我正在以编程方式添加TextViews，如下所示：

LinearLayout suggestions = (LinearLayout)findViewById(R.id.suggestions);
suggestions.setVisibility(View.VISIBLE);
suggestions.removeAllViews();
for(String completion : completions){
    TextView show = new TextView(DailyboothBoothView.this);
    show.setTag(completion + " ");
    show.setText("@" + completion);
    show.setPadding(5, 5, 5, 5);
    show.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v) {
        // Some code here   
        }
    });
    show.setHeight(show.getLineHeight() + 10);
    show.setTextColor(Color.parseColor("#cc6600"));
    suggestions.addView(show);
}

Answer 1

让视图执行测量并删除show.setHeight(show.getLineHeight() + 10)。看起来TextView在第一行文本之前有一些内部额外的填充，你没有考虑到这一点。

Answer 2

尝试更换：

suggestions.addView(show);

使用：

suggestions.addView(show, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));

TextView内容的一部分不可见
