Question

如何为每行设置不同的颜色？数据从SQLite到table layout，行数不固定。我想将第一行设置为green，将第二行设置为red，将第三行设置为red ...我已在color.xml上声明颜色，但它们不是工作...

DisplayData.java

// outer for loop
for (int i = 0; i < rows; i++) {

    TableRow row = new TableRow(this);
    row.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
            ViewGroup.LayoutParams.WRAP_CONTENT));

    // inner for loop
    for (int j = 0; j < cols; j++) {

        TextView tv = new TextView(this);
        tv.setLayoutParams(new TableRow.LayoutParams(
                ViewGroup.LayoutParams.WRAP_CONTENT,
                ViewGroup.LayoutParams.WRAP_CONTENT
        ));
       // tv.setBackgroundResource(R.drawable.cell_shape);
        tv.setGravity(Gravity.CENTER);
        tv.setTextSize(18);
        tv.setPadding(0, 5, 0, 5);

        tv.setText(c.getString(j));

        row.addView(tv);
        row.setBackgroundResource(R.drawable.color);

        row.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                Intent intent = new Intent(DisplayData.this, UpdatePage.class);
                intent.putExtra("name", name2);
                intent.putExtra("date",date2);
                startActivity(intent);
            }
        });

    }

    c.moveToNext();

        table_layout.addView(row);


    }
    sqlcon.close();
}

    }

color.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <resources xmlns:android="http://schemas.android.com/apk/res/android">
        <color android:name="green">#00ff00</color>
        <color android:name="red">#FF0000</color>
    </resources>

</LinearLayout>

可能有一个更好的解决方案，但我想这可行：

// outer for loop
   int colorIndex = 0;

   for (int i = 0; i < rows; i++) {

        if (index == 0)
        {
            //set background
            row.setBackgroundColor(getResources().getColor(R.color.some_color));
            index++;
        }

        else if (index == 1)
        {
            //set background
            row.setBackgroundColor(getResources().getColor(R.color.some_other_color));
            index++;
        }
        if (index == 2)
        {
            //set background
            row.setBackgroundColor(getResources().getColor(R.color.yet_another_color));
            index = 0;
        }
}
