我有一个警报对话框,当有人触摸特定按钮时会启动它。警报对话框包含一个由布局 xml 文件定义的视图。此布局包含多个控件,例如复选框、编辑文本字段……这些控件都位于滚动视图中,因此如果整个内容不适合屏幕,您可以滚动浏览内容。
现在的问题是,当我启动此警报对话框时,底部的按钮被截断了屏幕。尽管滚动条正在工作并且我可以滚动浏览警报对话框的内容,但有时警报对话框的按钮并不完全可见。
这意味着:有时,一切都很好,我可以看到警报对话框的按钮,有时出于奇怪的原因,按钮被切断了。我认为这是一个视图对于警报对话框来说太大并且将按钮向下推的问题。例如,视图包含一个编辑文本控件。如果我在那里输入我的名字,一切都很好。但是如果我在这个编辑文本中添加一个新行,按钮就会开始被剪掉一点。我做错了什么?我认为滚动视图会处理我的视图的超大尺寸,以便警报对话框适合屏幕。我的应用程序始终处于纵向模式。
视图代码:

这就是我启动警报对话框的方式:
final AlertDialog.Builder alert = new AlertDialog.Builder(QuizEditor.this);
alert.setTitle(getString(R.string.speichernUndVorschau) + "...");
alert.setMessage("");
LayoutInflater inflater = LayoutInflater.from(QuizEditor.this);
final View layFrage = inflater.inflate(R.layout.layoutquizsettings,null);
alert.setView(layFrage);
final CheckBox chkModeration = (CheckBox) layFrage.findViewById(R.id.chkModerationMode);
final CheckBox chkPassOver = (CheckBox) layFrage.findViewById(R.id.chkPassOver);
final CheckBox chkBlackScreen = (CheckBox) layFrage.findViewById(R.id.chkBlackScreen);
final EditText edtTeam1 = (EditText) layFrage.findViewById(R.id.edtTeam1);
final EditText edtTeam2 = (EditText) layFrage.findViewById(R.id.edtTeam2);
final EditText edtTeam3 = (EditText) layFrage.findViewById(R.id.edtTeam3);
final EditText edtTeam4 = (EditText) layFrage.findViewById(R.id.edtTeam4);
alert.setNeutralButton(getString(R.string.speichernUndVorschau), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
}
});
alert.setNegativeButton(getString(R.string.abbrechen), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
final AlertDialog dialog2 = alert.create();
dialog2.setOnShowListener(new OnShowListener() {
@Override
public void onShow(DialogInterface dialog) {
// TODO Auto-generated method stub
Button btnStarten = (Button) dialog2.getButton(AlertDialog.BUTTON_NEUTRAL);
btnStarten.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
ArrayList<String> teams = new ArrayList<String>();
String team1 = edtTeam1.getText().toString().trim();
String team2 = edtTeam2.getText().toString().trim();
String team3 = edtTeam3.getText().toString().trim();
String team4 = edtTeam4.getText().toString().trim();
if(team1.length() > 0) teams.add(team1);
if(team2.length() > 0) teams.add(team2);
if(team3.length() > 0) teams.add(team3);
if(team4.length() > 0) teams.add(team4);
if(teams.size() == 0) {
Toast.makeText(QuizEditor.this, getString(R.string.keinteameingegeben), Toast.LENGTH_SHORT).show();
}
else
{
// Quiz starten
dialog2.dismiss();
Intent myIntent;
if(chkBlackScreen.isChecked()) {
myIntent = new Intent(QuizEditor.this, BlackScreen.class);
}
else // Direkt das Quiz starten
{
myIntent = new Intent(QuizEditor.this, Quiz.class);
}
myIntent.putStringArrayListExtra("teams", teams);
myIntent.putExtra("moderation", chkModeration.isChecked());
myIntent.putExtra("passover", chkPassOver.isChecked());
myIntent.putExtra("filename", filename);
QuizEditor.this.startActivity(myIntent);
}
}
});
}
});
dialog2.show();
// dialog2.getWindow().setLayout(LayoutParams.WRAP_CONTENT, 300);
