如何在alertDialog上添加表布局

Question

我想创建自定义对话框与表视图，但对话框不显示当我点击按钮。这是在按钮的onClick侦听器.....中调用的方法

public void dialogTable(){
    int i;
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    LayoutInflater inflater = LayoutInflater.from(this);
    View alertView = inflater.inflate(R.layout.table_dialog, null);
    builder.setView(alertView);
    TableLayout tableLayout = (TableLayout)alertView.findViewById(R.id.tableLayout);
    TransactionDetails transactionDetails = new TransactionDetails();   //POJO class
    for( i=0; i < 4; i++ ){
        TableRow tableRow = new TableRow(getBaseContext());
        tableRow.setLayoutParams(new LinearLayout.LayoutParams
                (LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
        TextView textView1 = new TextView(getBaseContext());
        textView1.setText(transactionDetails.getCustomerNo());
        tableRow.addView(textView1);
        TextView textView2 = new TextView(getBaseContext());
        textView2.setText(transactionDetails.getAmount().toString());
        tableRow.addView(textView2);
        TextView textView3 = new TextView(getBaseContext());
        textView3.setText(transactionDetails.getStatus());
        tableRow.addView(textView3);
        tableLayout.addView(tableRow);
    }
    builder.setCancelable(true);
    AlertDialog alertDialog = builder.create();
    alertDialog.show();
}

我认为这个错误是你使用了错误的上下文来膨胀你的布局。您必须使用构建器上下文作为文档:

您必须使用相同的上下文来创建小部件。下面的代码是:

public void dialogTable(View view)
{
    int i;
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    Context dialogContext = builder.getContext();
    LayoutInflater inflater = LayoutInflater.from(dialogContext);
    View alertView = inflater.inflate(R.layout.table_dialog, null);
    builder.setView(alertView);
    TableLayout tableLayout = (TableLayout)alertView.findViewById(R.id.tableLayout);
    TransactionDetails transactionDetails = new TransactionDetails();
    for( i=0; i < 4; i++ ){
        TableRow tableRow = new TableRow(dialogContext);
        tableRow.setLayoutParams(new LinearLayout.LayoutParams
                                         (LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
        TextView textView1 = new TextView(dialogContext);
        textView1.setText(transactionDetails.getCustomerNo());
        tableRow.addView(textView1);
        TextView textView2 = new TextView(dialogContext);
        textView2.setText(transactionDetails.getAmount().toString());
        tableRow.addView(textView2);
        TextView textView3 = new TextView(dialogContext);
        textView3.setText(transactionDetails.getStatus());
        tableRow.addView(textView3);
        tableLayout.addView(tableRow);
    }
    builder.setCancelable(true);
    AlertDialog alertDialog = builder.create();
    alertDialog.show();
}

首先你应该检查你的按钮的监听器是否正确，其次你应该尝试设置TextView的文本颜色。

textView.setColor(Color.BLACK);
